Where have all the codfish gone?
The mega-decline in cod and other fisheries across the North Atlantic Ocean threatens the livelihood of fishermen and communities in New England and Atlantic Canada. One suspect in the disappearance of cod and other groundfish is the food source for their young: a planktonic copepod crustacean. The first transcriptome for the key North Atlantic copepod Calanus finmarchicus has been published; scientists will use it to decode the genetic instructions that are resulting in population changes.

Ecotoxicity: All clear for silver nanoparticles?
It has long been known that, in the form of free ions, silver particles can be highly toxic to aquatic organisms. Yet to this day, there is a lack of detailed knowledge about the doses required to trigger a response and how the organisms deal with this kind of stress. To learn more about the cellular processes that occur in the cells, scientists from the Aquatic Research Institute, Eawag, subjected algae to a range of silver concentrations.

Smithsonian scientists solve 'sudden death at sea' mystery
Modern whale strandings can be investigated and their causes identified. Events that happened millions of years ago, however, are far harder to analyze -- frequently leaving their cause a mystery. Smithsonian and Chilean scientists examined a large fossil site in the Atacama Desert of Northern Chile -- the first definitive example of repeated mass strandings of marine mammals in the fossil record. It reflected four distinct strandings over time, indicating a repeated and similar cause: toxic algae.

It's all water over the dam -- but how and when it falls has huge impact on salmon
By adjusting water discharges in ways designed to boost salmon productivity, officials at a dam in central Washington were able to more than triple the numbers of juvenile salmon downstream of the dam over a 30-year period. The research shows that keeping eggs and young salmon under water at especially vulnerable times boosts survival.

New digital atlas details Alaska sea ice history since 1860
A new web portal provides access to 160 years of historical sea ice concentration data for Alaska's Beaufort, Chukchi, and Bering seas, and allows users to view and download sea ice concentration data from 1850 to the present. This data set provides researchers with a reliable tool to evaluate climate change impacts.

EARTH Magazine: Tsunamis from the sky
Only recently have scientists unraveled how a storm can create and propagate these far-traveling waves -- called meteorological tsunamis or meteotsunamis. The waves, which arise out of a complex interplay of storm speed, wave dynamics and ocean-bottom bathymetry, may be less common than seismic tsunamis, but they can still be destructive and deadly.

Biomedical bleeding affects horseshoe crab behavior
New research indicates that collecting and bleeding horseshoe crabs for biomedical purposes causes short-term changes in their behavior and physiology that could exacerbate the crabs' population decline in parts of the East Coast.
