Excerpts;

Residents of Jakande Estate, Lekki, have raised an alarm over the spreading erosion on the beach, about 500 metres away from the sea, which they say threaten their lives.

The residents said the erosion was noticed five months ago, and that it might be caused by a stranded ship that has not been removed since a February storm washed some ships ashore.

The culprit ship, named MT Ray, is one of the 16 vessels washed ashore on February 14 but has now sunk deeply into the sea…

Excerpt;

The US’s ability to detect and forecast tsunamis has improved since the 2004 Indian Ocean tsunami, but current efforts are still not sufficient to meet challenges posed by tsunamis generated near land that leave little time for warning, says a new congressionally requested report from the National Research Council.

The report calls for a comprehensive national assessment of tsunami risk and improved communication and coordination among the two federal Tsunami Warning Centers, emergency managers, media, and the public…

Excerpts;

Plaquemines Parish officials are continuing to investigate a fish kill discovered Thursday.

P.J. Hahn, coastal zone director for the parish, said the parish would like to see more testing of the area where the kill was reported to determine whether oil from the BP spill contributed to the kill, as well as earlier fish kill reported last week…

Excerpts;

On the Waikiki shoreline, what’s here today will be gone tomorrow. From Kuhio Beach to the Royal Hawaiian Hotel erosion works overtime.

The loss rate’s about one to two feet a year.

The state wants to replenish 24,000 cubic yards of sand, bringing it in from 2,000 feet off shore to widen the beach by 37 feet…

Excerpts From Texas University, in ScienceDaily

In the aftermath of the Deepwater Horizon disaster in the Gulf of Mexico, a team of scientists led by UC Santa Barbara’s David Valentine and Texas A&M University’s John Kessler embarked on a research cruise with an urgent mission: determining the fate and impact of hydrocarbon gases escaping from a deep-water oil spill…

Melting sea ice forces walruses ashore in Alaska

http://www.youtube.com/watch?v=5B0JT6Qbp-E&feature=player_embedded
Massive super-herds of walrus are being forced onto dry land because of a lack of sea ice, the World Wildlife Fund reports. Discovery News UGC video shows an estimated 10,000 animals gathered in Point Lay, Alaska. Watch: A Youtube Video. Uploaded on September 17th, 2010.

Excerpts;

Tens of thousands of walruses have come ashore in northwest Alaska because the sea ice they normally rest on has melted.

Federal scientists say this massive move to shore by walruses is unusual in the United States. But it has happened at least twice before, in 2007 and 2009…

Expanding Hypoxic Areas in Coastal Waters

Coastal Hypoxia NASA
Off the coast of Oregon, a large dead zone—an area of water where the oxygen concentration is so low that little to no marine life can survive—has been appearing each summer since 2002.
NASA

Excerpts;

A report issued September 3rd, by key environmental and scientific federal agencies, assesses the increasing prevalence of low-oxygen “dead zones” in U.S. coastal waters and outlines a series of research and policy steps that could help reverse the decades-long trend.

The interagency report notes that incidents of hypoxia, a condition in which oxygen levels drop so low that fish and other animals are stressed or killed, have increased nearly 30-fold since 1960. Incidents of hypoxia were documented in nearly 50 percent of the 647 waterways assessed for the new report, including the Gulf of Mexico, home to one of the largest such zones in the world.

The impact of the BP Deepwater Horizon oil spill on oxygen levels in the Gulf of Mexico was not considered in this report because the spill had not yet occurred at the time the report was completed. Only additional research will reveal how the presence of oil in the gulf is affecting the large dead zone that forms every summer to the west of the Mississippi delta (see fact sheet), the more than 100 other independent sites along the Gulf of Mexico coast that experience low-oxygen problems, and areas of naturally-occurring deepwater oxygen depletion…

Dead Zones or Hypoxic areas Worldwide, NASA
The cause of anoxic bottom waters is fairly simple: the organic matter produced by phytoplankton at the surface of the ocean (in the euphotic zone) sinks to the bottom (the benthic zone), where it is subject to breakdown by the action of bacteria, a process known as bacterial respiration. The problem is, while phytoplankton use carbon dioxide and produce oxygen during photosynthesis, bacteria use oxygen and give off carbon dioxide during respiration. The oxygen used by bacteria is the oxygen dissolved in the water, and that’s the same oxygen that all of the other oxygen-respiring animals on the bottom (crabs, clams, shrimp, and a host of mud-loving creatures) and swimming in the water (zooplankton, fish) require for life to continue.
The dead zones are areas in the ocean where it appears that phytoplankton productivity has been enhanced, or natural water flow has been restricted, leading to increasing bottom water anoxia.

The 26th Annual California Coastal Cleanup Day is also Saturday, September 25th, 2010

California Coastal Commission
In 2009, more than 80,600 volunteers worked together to collect more than 1,300,000 pounds of trash and recyclables from our beaches, lakes, and waterways. California Coastal Cleanup Day has been hailed by the Guinness Book of World Records as “the largest garbage collection” (1993). Since the program started in 1985, over 800,000 Californians have removed more than 14 million pounds of debris from our state’s shorelines and coast…

New York City and Risk of Higher Seas

Excerpts;

When major ice sheets thaw, they release enough fresh water to disrupt ocean currents world-wide and make the planet wobble with the uneven weight of so much meltwater on the move. Studying these effects more closely, scientists are discovering local variations in rising sea levels, and some signs pointing to higher seas around metropolitan New York…
