ScienceDaily (July 9, 2010) - Alarm at the massive oil plume in the Gulf of Mexico emphasizes the problem of marine pollution and how difficult it is to evaluate. Thanks to a EUREKA project, another heavily polluted maritime ecosystem, the European North Sea, has been for more than 20 years a test-bed for a highly advanced early-warning system for all types of pollution. This development is now aiding marine authorities around the world to keep seas clean.

Alaska - NOAA determines "orange goo" in Alaska's Kivalina village is fungal spores
The "orange goo" that washed ashore earlier this month in the remote Eskimo village of Kivalina along Alaska's northwest coast is fungal spores, not microscopic eggs as preliminary analysis indicated. Scientists at the NOAA Alaska Fisheries Science Center's Auke Bay Laboratory announced last week that the substance was biological in nature, rather than oil or pollution as originally thought by concerned residents of Kivalina. Per standard scientific procedure, samples were sent to NOAA's Analytical Response Team for a more thorough and detailed analysis and verification process.
At NOAA's National Ocean Service Center for Coastal Environmental Health and Biomolecular Research, based in Charleston, S.C., a team of scientists highly-specialized and equipped to analyze microbiologic phenomena such as this determined that the substance is consistent with spores from a fungi that cause rust, a disease that infects only plants causing a rust-like appearance on leaves and stems. Rust fungi reproduce to infect other plants by releasing spores which disperse often times great distances by wind and water. However, whether this spore belongs to one of the 7,800 known species of rust fungi has not yet been determined. More information will be posted on the Alaska Fisheries Science Center website as it becomes available.

Abstract
The relative abundance of nitrate (N) over phosphorus (P) has increased over the period since 1980 in the marginal seas bordering the northwestern Pacific Ocean, located downstream of the populated and industrialized Asian continent. The increase in N availability within the study area was mainly driven by increasing N concentrations and was most likely due to deposition of pollutant nitrogen from atmospheric sources. Atmospheric nitrogen deposition had a high temporal correlation with N availability in the study area (r = 0.74 to 0.88), except in selected areas wherein riverine nitrogen load may be of equal importance. The increase in N availability caused by atmospheric deposition and riverine input has switched extensive parts of the study area from being N-limited to P-limited. "
Discovering what happens to the huge amounts of carbon - an estimated 2 megatons a year off the Oregon coast alone - is critical to understanding the interface between the atmosphere and the open ocean that influences marine dead zones, atmospheric pollution and ultimately climate change.
In this bracing talk, coral reef ecologist Jeremy Jackson lays out the shocking state of the ocean today: overfished, overheated, polluted, with indicators that things will get much worse. Astonishing photos and stats make the case.
Scientists have identified the 20 most important regions of the world's oceans and lakes that are key to ensuring the survival of the planet's marine mammals such as seals and porpoises. Their analysis also shows, however, that most of these areas are already under pressure from human impacts such as pollution and shipping.

20th anniversary International Coastal Cleanup
The Ocean Conservancy promotes healthy and diverse ocean ecosystems and opposes practices that threaten ocean life and human life. Through research, education, and science-based advocacy, The Ocean Conservancy informs, inspires, and empowers people to speak and act on behalf of the oceans. In all its work, The Ocean Conservancy strives to be the world's foremost advocate for
the oceans.
The International Coastal Cleanup engages people to remove trash and debris from the world's beaches and waterways, to identify the sources of debris, and to change the behaviors that cause pollution.
