Reef Life of the Andaman (full marine biology documentary)

31 October 2012

“Reef Life of the Andaman” is a documentary of the marine life of Thailand and Burma (Myanmar).

Scuba diving more than 1000 times from the coral reefs and underwater pinnacles of Thailand‘s Similan Islands, Phuket, Phi Phi Island and Hin Daeng, to Myanmar’s Mergui Archipelago and Burma Banks, I encountered everything from manta rays to seahorses, whale sharks to shipwrecks. The 116-minute film features descriptions of 213 different marine species including more than 100 tropical fish, along with sharks, rays, moray eels, crabs, lobsters, shrimps, sea slugs, cuttlefish, squid, octopus, turtles, sea snakes, starfish, sea cucumbers, corals, worms etc..

This marine biology documentary provides an overview of Indian Ocean aquatic life.

Reef rehab could help threatened corals make a comeback

Solutions for threatened reefs vary by location and damage done

Coral reefs are bustling cities beneath tropical, sunlit waves. Thousands of colorful creatures click, dash and dart, as loud and fast-paced as citizens of any metropolis.

Built up in tissue-thin layers over millennia, corals are the high-rise apartments of underwater Gotham. Calcium carbonate skeletons represent generations of tiny invertebrate animals, covered in a living layer of colorful coral polyps. Their structures offer shelter, and for about 114 species of fish and 51 species of invertebrates, those coral skyscrapers are lunch.

Important as they are, corals are in jeopardy. Warming oceans are causing more and more corals to bleach white and become vulnerable to destruction. A prolonged spike in temperatures, just 1 to 2 degrees Celsius, is enough to kill the marine animals. Greenhouse gas emissions also acidify the water, dissolving the calcium skeletons. In some countries, fishermen use dynamite to catch fish, leaving behind coral rubble. Today, more than 60 percent of the world’s reefs are at risk of disappearing.

Threats to reefs have “dramatically escalated in the last few decades,” says marine scientist Peter Harrison of Southern Cross University in Lismore, Australia. He has studied corals for three decades. “In my time as a reef researcher,” Harrison says, “I’ve seen it get worse, firsthand.”

Thirty years ago, massive coral bleachings were unheard of. Today, reefs are suffering through a third global bleaching event since 1998. With high ocean temperatures dragging on since 2014, this summer marked the longest and most widespread episode of worldwide coral bleaching on record (SN: 7/23/16, p. 5). Australia has been hit especially hard. More than 80 percent of the northern part of the Great Barrier Reef is bleached and close to half of those corals have died, according to a report in April from Australia’s National Coral Bleaching Taskforce.

As reefs take a nose dive, scientists from Hawaii to the Philippines and the Caribbean are scrambling to save corals. Approaches that were once considered radical are “now seen as necessary in some places,” says coral biologist Ruth Gates of the Hawaii Institute of Marine Biology on Oahu.

In Florida, researchers are restoring reefs with tiny coral fragments. In Hawaii, Gates is scouring the water for stress-tolerant corals and experimenting in the lab to breed the hardiest individuals. At the 13th International Coral Reef Symposium in Honolulu in June, Harrison’s team reported early promising results of its effort to flood damaged reefs in the Philippines with tiny coral larvae.

What works on one reef won’t necessarily save another. So researchers are testing an arsenal of options to rescue a diversity of underwater communities.

Rare chance at never-before-studied Kimberley reef

January 4, 2016 by Samille Mitchell

The weather gods conspired to provide a rare chance to survey a remote and rarely visited section of north Kimberley reef recently, with footage that will inform the future study of reefs through climate change.

Department of Parks and Wildlife (DPAW) researchers and Wunambal Gaambera traditional owners took advantage of the rare weather conditions to visit East Holothuria Reef, about 30km from the tip of Bougainville Peninsula, to conduct coral surveys.

They uncovered a flourishing and extremely biodiverse reef system, resplendent with corals and fishes, in a spectacular and never-before-studied part of the Kimberley’s underwater world.

“It is right in the top corner of the Bougainville Peninsula where wind-against-tides creates very rough sea conditions for much of the time,” says DPAW research scientist Andrew Halford.

“But we lucked-in with glass-off weather during neap tides—it was like a good perfect storm.”

The team traversed multiple 100-metre transects of the reef placing a camera on the bottom every 10 metres, which took photos every five seconds to record the diversity of the coral community.

Such footage will be used as a benchmark at monitoring sites across the north Kimberley, to enable conservation managers to study how reefs change and respond to different circumstances such as storms or a changing climate.

“We will be establishing long-term monitoring sites in the Kimberley that we can go back to and keep track of over time,” Dr Halford says.

“We’ll be able to see whether healthy reef communities can adapt to changing conditions over time.”

The big picture

The DPAW survey was part of a much larger examination of Kimberley benthic communities conducted by the Australian Institute of Marine Science, CSIRO, and the WA Museum, under the WA Marine Science Institute-managed Kimberley Marine Research Program.

These organisations are using large research vessels to study the diversity of the Kimberley marine benthic environment. The DPAW survey complimented their work by assessing shallower near-shore areas that are inaccessible to the larger boats.

Dr Halford says traditional owners are also playing an important role in monitoring these remote marine systems.

“As well as providing traditional knowledge of these areas, the idea is that eventually traditional owner groups will go out and do the surveying themselves,” Dr Halford says.

“They can take the footage and then the images can be sent to experts for analysis.”

Landmark victory for the Reef, and people power, as dredge spoil dump ban passed in Qld Parliament

Posted on 12 November 2015

New laws banning the sea dumping of industrial dredge spoil have passed in the Queensland Parliament in one of the most significant conservation victories ever for the Great Barrier Reef, said WWF-Australia and the Australian Marine Conservation Society.

WWF-Australia CEO Dermot O’Gorman said that, for more than a century, dumping huge amounts of dredge spoil in Reef waters was the norm. But the continuing decline of Australia’s national icon sparked an international campaign to end this out-dated practice.

“For everyone around the world who cares about the Reef this is a moment to savour,” said Mr O’Gorman.

“We’ve stopped up to 46 million cubic metres of dredge spoil from being dumped in Reef waters in coming years.

“That’s enough dredge spoil to fill 4.6 million dump trucks. If you lined those trucks up end-to-end on Highway 1 they would circle Australia three times.

“This is a huge win for people power. We thank the scientists, mums and dads, Australians young and old, and concerned citizens around the world who have all contributed to this victory. And we thank the Federal and Queensland Governments for listening and acting,” he said.

AMCS Reef Campaign Director Imogen Zethoven said: “The dumping ban becoming law sits alongside the establishment of the Great Barrier Reef Marine Park, the World Heritage Area and the green zones as landmark moments for Reef protection”.

In June the Federal Government banned the dumping of dredge spoil in the Great Barrier Reef Marine Park. But in recent years about 80% of dumping has occurred outside the park, closer to shore. The Queensland Government’s Sustainable Ports Development Bill now extends protection to the whole World Heritage Area. It also restricts major new capital dredging to Townsville, Abbot Point, Gladstone, and Hay Point/Mackay.

WWF-Australia and AMCS thanked the Liberal-National Party Opposition and two cross benchers for joining the government to support the Ports Bill.

“It’s particularly heartening to see genuine bipartisan support for the new law, since it fulfils key commitments made to the World Heritage Committee in the Reef 2050 Plan. The Queensland LNP should be congratulated for strengthening their position on Reef protection,” Ms Zethoven said.

Ms Zethoven said many challenges remained.

“The latest dredging plan for Abbot Point could be approved any day, the promised ban on transhipping has not yet been achieved, the Ports Bill doesn’t cover dumping of dredge spoil from smaller projects like marinas, and each year about one million cubic metres of spoil from maintenance dredging is dumped in Reef waters,” she said.

AMCS and WWF want to work with the Queensland Government to reduce that volume per year and minimise the impacts.
