Yellow-lipped Krait photgraphed on St. John's Island

Category : marine

This news from the lucky (well they keep their eyes open) guys who previously brought you photos of raptors and dolphins off St. John's Island.

This time, Chim Chee Kong writes,

"Hi Siva,

Me and my two colleagues (Lim Swee Cheng & Jeff Chouw) were very lucky to meet this amphibious sea snake (Laticauda colubrina) near the jetty of St. John's Island on last Friday (24 Jun 2005).

Staff of TMSI [Tropical Marine Science Institute, NUS] have had two previous encounters but this is the first time a photograph has been taken.

It was a cloudy morning (around 10am) with no raptors hovering above.

There were some bulges on the snake's body and the snake was twisting and turning "uncomfortably", so I guess it was digesting a meal.

Chee Kong"

The Yellow-lipped Sea Snake is also known as the Amphibious Sea Snake. Sea Debby Ng's underwater photo at the Hantu Blog, and read more about it at Ecology Asia and at Aquatic Snakes of Southeast Asia.

US Senators Introduce Ocean Trash Bill

Category : envt

"Senators Introduce Ocean Trash Bill." By Jeannette J. Lee, Associated Press, 14 Feb 2005; first seen on ENN.

HONOLULU A bipartisan group of U.S. senators from coastal states introduced legislation Thursday calling for removal of the thousands of tons of ocean debris that wash up on U.S. shores each year.

Sen. Daniel Inouye, D-Hawaii, and Sen. Ted Stevens, R-Alaska, said the bill is intended to protect marine ecosystems and human health from ocean-borne trash, including discarded fishing gear, equipment abandoned by commercial fleets and cargo that has washed overboard.

The measure would authorize up to $50 million over five years for a debris prevention and removal program at the National Oceanic and Atmospheric Administration, and up to $25 million over five years to strengthen Coast Guard enforcement of laws banning ship-based pollution.

Discarded long line nets and fishing line are most responsible for damaging coral reefs and killing marine animals, including seals, dolphins, turtles and seabirds, according to Seba Sheavly, director for the International Coastal Cleanup.

About 40 percent to 60 percent of debris collected in more than 100 countries during the program's annual worldwide cleanup is abandoned fishing gear, Sheavly said in a telephone interview from Virginia.

"A lot of fishermen are very responsible, but some are not," Sheavly said. "Fishermen by their trade and their own ethics don't want to leave their nets and gear behind. But things happen and there's not always disposal options for a damaged net out at sea or in port."

Isolation doesn't protect the largely uninhabited Northwestern Hawaiian Islands from mounds of ocean waste. Pacific currents funnel thousands of tons of refuse and debris to the eroded volcanic islands and atolls. When explorer Jean-Michel Cousteau visited the islands in 2003 he found hundreds of tons of trash and thousands of dead seabirds.

Seabirds find floating bits of plastic and bring them back to feed their young. They can accumulate as much as 10 ounces of plastic in their stomachs before they die, Cousteau has said. Larger debris, such as fishing gear, can trap endangered Hawaiian monk seals and threatened green sea turtles.

"In a high-tech era of radiation, carcinogenic chemicals and human-induced climate change, the problem of the trash produced by ocean-going vessels or litter swept out to sea must seem old-fashioned by comparison," said Inouye. "Regrettably, that perception is wrong."

Other sponsors include Sen. Maria Cantwell, D-Wash., and Sens. Olympia Snowe, R-Maine; John Kerry, D-Mass., and Frank Lautenberg, D-N.J., from Atlantic Coast states.

Dolphins off Pulau Senang, 4th January 2005

Category : marine

The pleasure of the first record of dolphins in Singapore waters in 2005 has been provided by a group from the NUS Marine Lab out on a dive trip in the southern islands of Singapore on 4th January 2005.

With them was Fran Saborido-Rey, a visiting researcher from Spain, who shot a 30 seconds video with his digital camera from the deck of The Mudskipper, the boat of the Department of Biological Sciences, NUS. [Link - 18.5MB avi file]

They watched several dolphins break the surface repeatedly. A smaller, shorter (13 seconds) clip, is provided here as a 7.7MB mov file.

To get a good look at the dorsal surface of the dolphins, it would be better to right-click and download the video to your desktop. Increase the size by double when you view it with a video player such as the free QuickTime Player (this is available for Windows as well).

The second sighting of a pod of dolphins in 2005 was reported earlier by Lim Swee Cheng, off St. John's Island, on 1st February 2005.

Thanks to Fran Saborido Rey for generously providing the video to the NUS Marine Lab, to Peter Todd for alerting me to this and for copying the video for me, Elsie Wong for the field trip date, Loh Tse-Lynn for the location and Dionne an November for corrections.

Dolphin's off St. John's island

Category : marine

Dolphin's were spotted by Lim Swee Cheng, on Tuesday, 1st February 2005. More details as the become available. But no photos this time, unfortunately!

See the famous sighting off St. John's Islands with photos, on 12 March 2004 and the sighting off Sister's Islands on 24 Jun 2004.

Dolphins sighting at Sisters islands on Tue 22 Jun 2004

Category : marine

"It was SO amazing to see dolphins frolicking in Singapore waters! They were doing flips and jumps, cocking half their bodies out of the water too! Approximately 10 of them were just playing around that area and we sat there and watched them for about half an hour. AMAZING!"

"It was an experience of a lifetime! Even when I saw dolphins in Australia, the feeling is different: to see dolphins in our own backyard, and in the wild, means so much more than to see it anywhere else."

- Jani Thuaibah, who was on a field trip with other members of the Marine Biology Lab, NUS Biological Sciences. She had left her camera behind that day, so Chim Chee Kong's photos are still the best we have of dolphins in local waters.

Sister's Islands are south-west of St. John's Islands, are also known as Pulau Subar laut and P. Subar Darat and are administered by Sentosa Development Corporation. Records of dolphin and other interesting sightings are also maintained at the "Anecdotal observations of marine life" page in the Coral Reefs of Singapore site.

Keep looking and reporting everyone!

Drowning in an ocean of plastic

Category : envt

Stephen Leahy writes about "Drowning in an ocean of plastic" in Wired News, 5th June 2004.

"The United Nations has turned its attention to the oceans for World Environment Day, and one of the main evildoers is a familiar one -- plastic. Marine trash, mainly plastic, is killing more than a million seabirds and 100,000 mammals and sea turtles each year, said U.N. Secretary-General Kofi Annan in a statement."

- Plastic bags, bottle tops and polystyrene foam coffee cups are often found in the stomachs of dead sea lions, dolphins, sea turtles and others.
- Fulmars, a type of seagull, had an average of 30 pieces of plastic in their stomachs.
- Big pieces of plastic look like jellyfish or squid, while small pieces look like fish eggs.
- Albatross parents fly huge distances to feed their young a deadly diet of plastic bottle caps, lighters and light sticks.
- In the middle of the North Pacific, six pounds of plastic found for every pound of algae.
- About 20 percent of the plastic in the oceans comes from ships or offshore platforms; the rest is blown or washed off the land.
- Plastic kill marine animals that eat it or get tangled in it and drown, but it also damages and degrades their habitat.
- Plastic can leach endocrine-disrupting chemicals like biphenyl A.
- Most plastics don't biodegrade.
- Microscopic pieces of plastic can even be found inside plankton, the keystone of the marine food chain.
- The amount of plastic particles in the oceans has at least tripled since the 1960s.

"It's just dawning on people that the oceans are in deep trouble."

Dolphins sighted off St John's Islands

Category : marine

"Yes Siva,

Dolphins were sighted once again in St. John's Island waters!!!

Date: Friday 12 Mar 2004. Time: 1200hrs - 1300hrs

Location: Channel between St. John's Island & Lazarus Island

Number: 5 adults and 1 juvenile. All grey except 1 white adult.

Environment condition: Relatively clear water, cool weather, quite sunny. Reclamation works still going on at Lazarus Island. Quite busy channel with vessels using the St. John's Island jetty.

The dolphins were less than 50 metres away from me at some point of time. I couldn't capture any close up photos as the camera I am using couldn't zoom far enough. Nevertheless, its still better than nothing!!


[Chim] Chee Kong"

The second, third and fourth photo were brightened.

Look carefully to see all six dolphins in the third photo.

This is a wonderful addition to our arsenal of answers to the question, "Is there marine life [worth protecting] in Singapore?"" Thanks Chee Kong!

Will they stay? Will we retain our battered marine life? It's going to be a challenge - ironicallly, today's Straits Times carried a report which says, "The Southern Islands - made up of the two Sisters Islands, Pulau Seringat, Lazarus Island and St John's Island - have already been enlarged by reclamation. They will be linked to Sentosa by boat or by a bridge, and further reclamation will be done to create the development." - ["Top-draw resort for southern isles." By Audrey Tan, Straits Times, Sat 13 Mar 2004]
