Hawaiian Reef Ecosystem


Coral reefs are the most biologically diverse marine eco-systems on earth, rivaled only by the tropical rainforests on land. Corals grow over geologic time and have been in existence about 200 million years. Corals reached their current level of diversity 50 million years ago.The delicately balanced marine environment of the coral reef relies on the interaction of hard and soft corals, sponges, anemones, snails, rays, crabs, lobsters, turtles, dolphins and other sea life.
A coral reef is composed of thin plates or layers of calcium carbonate secreted over thousands of years by billions of tiny soft bodied animals called coral polyps. It takes years for some corals to grow an inch and they range in size from a pinhead to a foot in length. Each polyp excretes a calcereous exo-skeleton and lives in a symbiotic relationship with a host algae, zooxanthellae, that gives the coral its color. Zooxanthellae takes in carbon dioxide, process is through photosynthesis, and then gives off oxygen as a by-product that is used by the host polyp. Millions of polyps grow on top of the limestone remains of former colonies to create the massive reefs. Yet these tiny animals form the only natural formation visible from outer space.
The ecology of coral reefs in Hawai'i is unique compared to reefs in other tropical areas. Hawaiian reefs are unique for several reasons:

1. They are geologically young and therefore not as well developed as other reefs. Most reefs in the windward islands of Hawai'i, Maui, O'ahu and Kaua'i are small and occur relatively close to shore. As these reefs grow and develop they are called fringing reefs, which eventually develop into barrier reefs, which occur in Kaneohe Bay on O'ahu and on the south shore of Moloka'i. There is a general westward trend towards greater reef development which coincides with the geologic ages of the islands. Superimposed upon this pattern, however, is the effects of wave exposure: in general more sheltered leeward coasts have reefs with greater coral cover than wave-pounded windward coasts (see Grigg, 1983).

2. As a consequence of their younger age and the general absence of barrier reefs in the windward islands, Hawaiian reefs are generally less productive than other reefs. With smaller reef areas and the absence of lagoons that trap and retain both coastal and terrestrial runoff, Hawaiian reefs are generally more nutrient poor and therefore lack a high abundance of filter feeding animals such as soft corals, sponges, tunicates, and bivalves. As a result, Hawaiian reefs are more clearly dominated by corals.

3. Due to the geographic isolation of the Hawaiian Islands they are less diverse that other reefs, especially those in the nearby Indo-Pacific province to which they belong. For example, in Hawai'i there are about 40 species of reef building corals; in the western Pacific island of Palua there are over 300! One consequence of lower diversity is that reef-building corals in Hawai'i are less specialized and thus more generalized in their distribution than species elsewhere. Furthermore, a relatively few number of corals dominant Hawaiian reefs. There is a unique advantage to science here, however, because Hawaiian reefs are far easier to study!
B. Coral Reef Zonation in Hawai'i
In response to variation in environmental conditions near the shoreline, coral reefs exhibit zonation where the abundance and composition of the coral community varies according to distance and depth from shore. Wave exposure is the primary factor causing zonation in Hawai'i but gradients in sedimentation, salinity, and temperature are also important (see Dollar, 1982). The following is a summary of zonation patterns typical of Hawai'i. Common names are linked to descriptions in the Marine Life of Hawai'i section.

More about corals

Corals are divided into two kinds and both are stationary on the ocean bottom. Hard corals such as brain, star, staghorn, elkhorn and pillar corals have rigid exoskeletons, or corallites, that protect their soft delicate bodies. Gorgonians, or soft corals, such as sea fans, sea whips, and sea rods, sway with the currents and lack an exoskeleton.

Coral reefs depend upon mangroves and sea grasses

Mangroves are salt-tolerant trees with submerged roots that are a nursery and breeding ground for birds and most of the marine life that migrates to the reef. Mangroves trap and produce nutrients for food and habitat, stabilize the shoreline, and filter pollutants from the landbase.
Seagrasses are flowering marine plants that are an important part of the food web. They provide foods and habitat for turtles, manatees, many fish, filter-feeding organisms and foraging sealife such as sea urchins and sea cucumbers. Seagrasses are a nursery for pink shrimp, lobster, snapper and other sealife. They filter the water of sediments, release oxygen and stabilize the bottom.

Where are coral reefs located?

Coral reefs occupy less than one quarter of one percent of the earth's marine environment, yet they are home to more than a quarter of all known fish species.

Why is thecoral reef important?Coral reefs deserve protection for their intrinsic natural value. In addition, the economic, tourism, fishing and recreational resources of tropical areas around the world depend upon healthy coral reef ecosystems. Barrier coral reefs protect shorelines from erosion and storm damage.

The food, tourism revenue, coastal protection and new medications that reefs provide are worth about $375 billion each year.

Why does the coral reef need protection?Reefs at Risk: A Map-based Indicator of Threats to the World's Coral Reefs, produced by the World Resources Institute (WRI at http://www.wri.org/) in collaboration with the International Center for Living Aquatic Resources Management (ICLARM), the World Conservation Monitoring Centre (WCMC) and the United Nations Environment Programme (UNEP), is the first goal assessment of coral reefs to map areas at risk from overfishing, coastal development, and other human activity ranging from coastal development and overfishing to inland and marine pollution -- leaving much of the world's marine biodiversity at risk.

Coral reefs are suffering globally. Scientists report that 30% are already damaged. Corals grow only in warm tropical waters ideally between 70-85 degrees Fahrenheit. Although climatic and geological changes affect them, human activities have had far greater consequences over the past decade.

The first generation to discover scuba may be the last to enjoy coral reefs, if we don't get involved. Corals are damaged by a variety of physical impacts that include anchor damage, accidental boat groundings, and diver/snorkeler touching, standing and dragging equipment. Propellors tear up shallow seagrasses. Marine debris, especially plastics, damage marinelife and smother corals. Turtles mistake plastic bags for their favorite food, jellyfish.

Water quality declines when pollution discharges from boars or coastal areas reduce visibility and oxygen and increase chlorophyll levels, causing a proliferation of new coral diseases and massive algal blooms. Coral bleaching occurs when sea temperatures rise or other stresses occur and the corals expel their symbiotic algae.

Siltation from coastal development and beach renourishment smothers fragile corals. Agricultural run-off that contains pesticides and fertilizers add toxins and nutrients to reefs that require nutrients-free waters to thrive. Overdevelopment and lack of sewage and stormwater infrastructure in coastal areas is a leading source of damage to reefs.
Outright habitat loss occurs when coral and live rock is harvested for construction or the aquarium/curio trade. Destructive fishing techniques and overharvesting of fish and tropical marinelife is a worldwide problem.

Spinner Dolphin


Spinner Dolphin Pictures, Behaviors, Video and Information (provided by the Wild Dolphin Foundation)

The Hawaiian name for dolphin is nai'a, and refers to most all dolphins found here. Hawaiian Spinner dolphins are shaped and colored somewhat differently from other species of spinner dolphins.
With 13 species of toothed dolphins (nai'a) swimming in the tepid waters of Hawaii, the most common are the Hawaiian spinner, spotted (kiko), bottlenose and rough-toothed dolphins. Other often seen members of the dolphin family - although termed as whales (kohola)- are pilot and false killer whales.

Dolphins in Hawaii are commonly termed as "porpoise" by local folks, especially fishermen, who use the word "dolphin" when referring to the dolphin fish, or mahi mahi.

So called for their high, spinning leaps, spinner dolphins are known as playful, eager bow-riders throughout much of their range.

In certain areas in Hawaii, spinner dolphins are seen on an almost daily basis. Probably since the islands have formed, the Hawaiian spinner dolphins have come into nearshore daytime habitats along the west coast of Oahu. We have traced their occurrence in our area back at least 800 years.

Below are descriptions of daytime behaviors the acrobatic spinners frequently engage in. Pictures and videos were taken during our dolphin encounter tours.

Hawaiian Spinner Dolphins Stenella longirostris "Nai'a"Size: 1.7 to 2.2 m, 75 kg. Males slightly larger than females Calves at birth: 77 cm 45 to 65 sharp-pointed teeth on each side of upper and lower jaw Food: Fish (small deep-ocean species) and squid Habitat: Mainly offshore Range: Tropical, subtropical and warm temperate world ocean Status:
Population unknown, but common in most parts of its range. Substantial declines have occurred in the eastern tropical Pacific

Spins
Spinner dolphins are famous for their fantastic jumps high out of the water. They can leap into the air and make as many as 7 complete spins before diving back into the ocean! Few dolphins are known to leap as high as the Spinner and except occasionally for the Clymene dolphin, no others spin. Why Do Spinner Dolphins Spin?Note: Click on the picture to the right to see good spin video >>

Head-Over-Tail
This aerial behavior is probably the most energetic. While the spin is more like a top, this leap is a series of mid-air somersaults.Note: Click on the picture to the right to see head over video >>

Head Slaps
This very young spinner has already learned a way to get mom's attention. Repeated head slaps send an acoustical message. Notice the pinkish underside, normally white, this could mean excitement or the product of vigorous slapping!

Tail or Peduncle Slaps
Often seen before a change in the pods behavior. Most often, immediately after we see this behavior, the pod will change its traveling direction. Tail slap video and how it looks from underwater. The dolphin is excited about his "play toy!"

Nose-Outs
Often seen before going into a rest mode, or when they seem to have interest in us. These, although still classified as aerial behaviors are the least energy taxing.

Fluke-up Dive
Dives with the tail (flukes) raised in the air seem to signal deep dives. This a borderline aerial behavior - as it still happens above the water line, but is not very active.

Playing Behavior
Spinners often make "play-toys" of objects in their environment. In our area, the tradewinds blow lightweight plastic grocery bags into the ocean. The dolphins drape these over their fins and pass them back and forth. Note: Click on the picture to the right to see dolphins play video >>

Echelon Swimming
Newborn calves can be seen swimming near their mothers head for about a week before they swim nearer to her dorsal fin. This is termed as echelon swimming. Dolphins carry their young inside their womb and gestation is about 12 months for a bottlenose. The baby emerges tail first, and will suckle from its mother for up to 4 years.

Breathing
Oceanic dolphins have evolved a method of breathing without surfacing from the water. They blow a bubble when near the water surface and then quickly draw breath in when the bubble forms a bridge between the blowhole and the air, through the water. Dolphins breathe through their blowhole located at the top of their head. A dolphin may empty and refill its lungs in less than a fifth of second. As the dolphin breathes the air leaves the blowhole at speeds of over 100mph. To sleep, a dolphin must shut down only half of its brain, as its breathing is under voluntary control.

Social Behavior
Spinner dolphin's pectoral flippers are used to steer them through the water, and they also use them to stroke one another, increasing the social bond between them. Dolphin "friends" may swim along face to face touching flippers. Dolphins that appear to be closely bonded may swim in synchrony, twisting, turning and swimming in perfect harmony together.

Whistles
Spinner Dolphins can be very noisy under and above water, click here to hear for underwater video and sound of spinner dolphins vocalizing and a signature whistle.

Our wildlife tours focus on education and conservation so that an interactive relationship can be maintained in the best interest of both humans and dolphins. We strive to foster admiration and deep respect for these wonder-ful marine mammals.

Whales! A Special Winter bonus...

Throughout the winter months (Jan-Apr), the Humpback Whales make the calm waters of the West shore of Oahu their home for mating and calving. You'll be thrilled to witness a variety of surface behaviors, such as spouts, dives, breaches, flipper and tail slappings, and to hear the intricate whale "songs" echoing in the ocean.

Week of 12/26 to 12/30 we seen 19 whales up close.. First time we seen so many pods in a general area. It was amazing and exciting. This is also a great time to swim and see spinner dolpins

Coral reef ecosystems

The coral reef ecosystems of the Northwestern Hawaiian Islands suffer from contamination by considerable amounts of derelict fishing gear, trash, pollution from North Pacific Ocean fisheries washed in by ocean currents.

Greenpeace released a report last week examining the "vast vortex of plastic trash in the middle of the Pacific Ocean," so described by Reuters. The report finds that the coral reef sytems of the NWHI, the endangered Hawaiian monk seal, and, worldwide, "at least 267 species -- including seabirds, turtles, seals, sea lions, whales and fish" are vulnerable to the contamination caused by tourism, sewage, fishing and waste from ships and boats. Derelict fishing gear includes, "fishing lines and nets, fishing pots and strapping bands from bait boxes that are lost accidentally by commercial fishing boats or are deliberately dumped into the ocean."
The research predicted that most debris is moved towards the mid-latitudes. This is in agreement with observations from other studies which showed higher concentrations of debris in such areas compared to nearer the poles. It also identified areas where ocean movements results in particularly high concentrations of debris such as north of Hawaii.

Living there part time, i have noticed in the last twenty years, the price of a nice piece of land is not what it once was.. While swimming in Maui, we came to a place called "BLACK ROCK" off Maui, the beach side was littered with trash, junk in the water and the water was nasty.. It wasnt like that ten years ago, but many people come to the islands and dirty them, destroy the beauty and leave. My daughter and i started doing cleanup work in the area with 30-50 other people and still seems we have along way to go.

Lost Baggage / Hawaii

So while on my trip to Maui, to dive with the dolphins and swim with the fat people. I made my way from California to Maui where i thought things were going to be exciting off the plane. To say the least. We arrived on 12/20/07 to spend the holidays over on the islands and was supprised to be standing at the luggage claim without my families gear, we sat there for 26 minutes along with about 100 people on 4-6 different airlines for us to have to goto the counter fighting our way to the manager to assist us in finding our bags. Not one bag but 9 bags for 5 people. Needless to say we didnt get it back for 3 days which was tough. Washing the same clothes and being cheap to buy new stuff, and spend that extra money during the holidays.

We made many calls 2-3 times a day to Aloha Airlines to get our stuff and was reported that there was 52 members still at the time of us getting our stuff that their stuff still didnt make it to islands.. I wish them the best and makes me want to carry this stuff on the plane with me next time. It was a good way to piss 5 family members off..

THE MONARCHY IN HAWAI‘I: A PROUD LEGACY REMEMBERED

THE MONARCHY IN HAWAI‘I: A PROUD LEGACY REMEMBERED

Author: Jeff Wilmot

Kamehameha the Great (born c. 1758, died 1819) set out from the Big Island in the last decade of the 18th century to conquer his neighbors. Kauai was the sole holdout and as some on the Garden Isle will proudly tell you, Kamehameha never succeeded in defeating the Kaua‘i chiefs. Nevertheless, Kaua‘i ceded power to Hawaii's powerful first king in 1810 and the Hawaiian Islands were joined.Kamehameha's son, Liholiho (1797-1819) succeeded him to become Kamehameha II.

His late father's favorite wife, Queen Ka‘ahumanu, however, wielded the real power. A feminist of sorts, the Queen systematically broke the age-old kapu (taboos) that restricted women's power in Hawaiian society.Around the same time, Kaahumanu was encouraging the end of the kapu system, the first wave of congregational missionaries arrived in Hawai‘i. The convergence of these forces set off another round of change with great effect.The next three monarchs were also crowned in the Kamehameha line: III (Kauikeaouli), IV (Alexander Liholiho) and V (Lot Kamehameha). Upon Lot’s death, William Lunalilo took the throne for one year.

In 1874, David Kalakaua was elected king under Hawaii's constitution. A champion of Hawaiian culture, Kalakaua was known as the "Merrie Monarch" because of his penchant for enjoying the good life. Among his accomplishments, Kalakaua built the grand Iolani Palace in Honolulu and revived the art of hula.

While Kalakaua was Hawaii's last king, his sister, Queen Liliuokalani, has the distinction of being Hawaii's last monarch. In a futile attempt to revert to an earlier Constitution and restore power to the monarchy, Liliuokalani was forced to step down during a coup by American businessmen. Thus, the Republic of Hawai‘i was born on July 4, 1894. Four years later, Hawai‘i became a territory of the United States.Today, Kamehameha is the name of a highway on Oahu, and Kalakaua is the name of the main thoroughfare in Waikiki.

Kaahumanu is the name of a shopping center in Maui. Still, Hawaii’s culture and heritage are revered by many in the Islands. The diverse populations that have made Hawai‘i their home in the last 100 years have adopted and embraced the Hawaiian spirit of aloha. You'll always be welcome in Hawaii.

SURFING OAHU'S NORTH SHORE CATCH A WINTER WAVE

SURFING OAHU'S NORTH SHORE CATCH A WINTER WAVE

Author: Lance Tominaga

Each winter, O‘ahu’s rugged North Shore serves up some of the largest and imposing ocean waves on the planet. Giant, storm-generated swells make their long trek across the northern Pacific to batter reef breaks and the area’s shoreline. For many Island residents, this means only one thing: Surf’s up!The exact origin of surfing is unknown, but most historians believe that the Polynesians were already well versed in the sport by the time they migrated to the Hawaiian Islands some 2,000 years ago. Early Hawaiians called surfing "he‘e nalu," which literally translates to "wave sliding."

During this time, only high-ranking ali‘i had access to the best surf spots. King Kamehameha himself was said to be an avid and skilled surfer.Surfing really took off in the early 1900s. Riding boards made mostly from hewn redwood and balsa wood, early surfers risked their lives to take on these giant waves.Today, thanks to a number of modern innovations and inventions, the surfing population on the North Shore has exploded. Wave riders and spectators from around the world gather here from November to February, hoping catch that perfect wave.

Winter wave heights can get as high 20 feet, with faces up to 50 feet! This extreme surf is for experts only, and even then conditions are considered highly dangerous. World-renowned surf contests are held here from early November to late December. The Van's Triple Crown of Surfing, which includes the Van's Hawaiian Pro at Ali'i Beach Park in Hale'iwa; the Rip Curl Cup at Sunset Beach; and the XBox Gerry Lopez Pipeline Masters, brings together the world’s best professional surfers.

The Quiksilver Eddie Aikau Big Wave Invitational, held at Waimea Bay, also takes place each winter. Although winter on the North Shore may not be the best time and place to learn how to surf, the summer months provide safer, saner conditions.Ask any surfer, and he (or she) will tell you that surfing is an exhilarating thrill, a natural high. "

I love the sensation of riding a wave and the feeling I have when I’m out on the ocean," says Hans Hedemann, a former pro surfer-turned-surfing instructor. "It’s also a challenge because every wave is different, and it’s up to me to make the most of each wave."

Scuba diving in Hawaii's choicest locations is an unrivaled experience. Bathed in the tepid crystalline depths of the azure Pacific, tethered by bubbles and brushed by rainbow colored fish, scuba divers enter a fantasy world of brilliance and wonder. Each of Hawai'i's eight main islands have outstanding dive spots with an array of unique marine animals, colorful corals and bizarre lava formations. Most diving occurs on the calmer, leeward coasts of all the islands, where visibility often exceeds 100 feet. Dive shops abound with gear rentals, dive trips, lessons and certification.

Five types of underwater habitats—coral reefs, lava tubes, caves and caverns, sandy bottoms, drop-offs and basalt boulders—create Hawaii's underwater terrain.Boat diving is one of the easiest ways to experience Hawai'i's underwater wilderness. Diving from the shoreline is dictated by ocean conditions, and is not recommended in high surf. Kaua'i and Ni'ihau: Kaua'i boasts 10 prime dive spots located on both the north and south shores of the island. From the Ha'ena area of the north shore, in summer months when the ocean is calm, Ke'e Lagoon, Tunnels Reef and Cannons offer shore diving in depths ranging from 12 to 65 feet.

South shore spots on Kaua'i offer intermediate to advanced boat dives including Sheraton Caverns, Brennecke's Drop-off and Oasis reef. A special attraction for advanced divers is the challenge of diving Ni'ihau, where monk seals, schools of dolphins and clouds of seabirds swarm above and below the crystalline sea. Hawai'i (The Big Island): Dive spots on the Big Island occur only along the leeward, Kona and Kohala coastlines. Cavern Point, Place of Refuge, Kailua Pier, Pine Trees and Red Hill are some of the favorites. Kona and Kohala coast dive spots range from novice to advanced with depth ranges of 10 to 130 feet. Maui, Lana'i, Moloka'i and Molokini Crater:

These islands are teeming with excellent dive sites. From the island of Maui, most dive spots are located on the western shore, and include Honolua Bay, Olowalu and Five Caves. A short boat ride to Molokini Crater, meanwhile, reveals four additional dive sites that occur along the rim of this ancient, sunken volcano. Highlights include black corals and schools of tame fish in depths of 10 to 130 feet. Lana'i has six popular dive sites on its south coast. All Lana'i dives are by boat. Moloka'i dives center around Mokuho'oniki Rock at the east end of the island.

Oahu: Waimea Bay, the Wai'anae coastline and Maunalua Bay offer popular dive attractions on O‘ahu. Hanauma Bay offers one of the island’s most breathtaking panoramas along with advanced, intermediate and novice dive sites accessible from shore.

SNORKELING IN HAWAII

SNORKELING IN HAWAII

If you think a land or aerial tour of Hawaii provides spectacular scenery, try taking in the views just below the ocean’s surface. Glide effortlessly along the gentle currents and see brilliantly colored fish, green sea turtles, exotic coral reef beds and more of Hawaii’s undersea life.There’s a whole new world under the ocean’s surface.Snorkeling is one of the most popular outdoor adventures in the Aloha State. And the good news is, there are great snorkeling spots on every island. The most popular snorkeling destination in the state is probably Hanauma Bay Nature Preserve on Oahu. Situated on the island’s southeast coast, Hanauma Bay is sheltered from strong currents and waves, making it an ideal spot for snorkeling. This isn’t exactly one of Hawaii’s best-kept secrets, however. About 3,000 visitors flock to the bay every day.

Other good snorkeling spots on Oahu include Queen’s Beach in Waikiki and Shark’s Cove on the North Shore. Shark’s Cove is a lava-edged pool filled with rainbow-colored tropical fish.Another famous snorkeling destination is Molokini islet, a volcanic cinder cone located about three miles off the shores of Maui. Molokini has crystal-clear waters (visibility usually exceeds a hundred feet) and abundant sea life: tropical fish, rays, eels and more. Molokini has been designated a Marine Life Conservation District Seabird Sanctuary.Other recommended snorkeling adventures on Maui can be found at Kapalua Bay, Honolua Beach and the legendary Black Rock in Kaanapali.The island of Lanai is renowned as one of the world’s premier snorkeling destinations. Head to Hulopoe Beach, where the best snorkeling is between the beach’s eastern point and the center of the bay (where the reef is most developed).

The Big Island offers a number of snorkeling spots. The best of them all might be Kealakekua Bay, a protected marine sanctuary filled with ocean life. Kealakekua Bay is accessible via boat charters.The island of Kauai also has a nice array of snorkeling opportunities. Favorite spots include Poipu Beach Park on the island’s south shore and Anini Beach on the north shore.

Snorkeling Tips:

Always snorkel in areas where there are other swimmers and snorkelers. Don’t snorkel near surfers. Avoid the water if it is murky, choppy or rough. Look up out of the water periodically to keep your bearing. Do not feed the fish (it clouds the water and can make the fish sick). It is against the law to harass or touch a green sea turtle or monk seal; both are protected by the Endangered Species Act.

Hawaiian Coast

The Hawaiian Coast features many diverse dive environments including lava tubes, caves, and arches. It is often worthwhile to go into caverns and lava tubes to see if there are any interesting critters hiding there. We can find sleeping sharks, nudibranchs, and other noctural animals there.

Come join us for a wonderful experience.

At Hawaii Reef Divers, the crew takes all the work out of diving. We set up your gear while you are checking in on the dock. When it's time to dive we make entering the water extremely simple and safe. A crewmember will carry your gear to the stern while you wait, seated, on one of two metal benches. All that's left is for you to strap on your tank and stride into the clear, calm waters. After your first dive enjoy fresh island fruit and a cool drink while the crew switches your gear over to a fresh tank. After your second dive your gear is rinsed for you as we motor back to the harbor. Our dives are guided by knowledgeable instructors who brief you on what to expect to see before you enter the water. Encounters with dolphin, turtles, and manta rays are common in the placid Hawaiian waters and other visitors make special appearances to assure that every dive can turn into something extraordinary and interesting to say.
