NOAA Dives into Puget Sound with Current Survey

This item was filled under News


Beginning May 28, 2015, NOAA's Center for Operational Oceanographic Products and Services (CO-OPS) will be performing a current survey throughout Puget Sound, the San Juan Islands, and the Strait of Juan de Fuca over the next three years. The observations collected during this survey will enable NOAA to provide tidal current predictions to commercial and recreational mariners that depend on this information for safe navigation.

Invisible helpers of the sea: Marine bacteria boost growth of tiny ocean algae

This item was filled under Climate
A common diatom grows faster in the presence of bacteria that release a growth hormone known to benefit plants on land. The authors of a new report showed that these bacteria exchange material with the diatoms while in turn producing auxin, a well-known hormone made by microbes living around the roots of land plants....

Global climate on verge of multi-decadal change

This item was filled under Climate
The global climate is on the verge of broad-scale change that could last for a number of decades a new study implies. The change to the new set of climatic conditions is associated with a cooling of the Atlantic, and is likely to bring drier summers in Britain and Ireland, accelerated sea-level rise along the northeast coast of the United States, and drought in the developing countries of the Sahel region....

Evolution of the Antarctic ice sheet

This item was filled under Climate
A new light has been shed on the stability of the Antarctic ice sheet. It shows for the first time that ice rises (pinning points that keep the floating parts of ice sheets in place) are formed during the transition between glacial and interglacial periods, which significantly slows down the response of the ice sheet to climate change....

Potential of seagrass to combating climate change

This item was filled under Climate
Seagrass ecosystems could play a key role in combating climate change, researchers have discovered. The marine flowering plant also helps sustain abundant sea life and protects shorelines around the world from coastal erosion. Yet with seagrass habitats suffering rapid global decline and despite the plant's huge potential; there are currently no functioning seagrass restoration or conservation projects. Due to their shallow coastal habitat the aquatic plant is particularly prone to human disturbance - globally 24 per cent of seagrass species are now classified as threatened or near threatened....

Climate engineering may save coral reefs, study shows

This item was filled under Climate
Mass coral bleaching, which can lead to coral mortality, is predicted to occur far more frequently over the coming decades, due to the stress exerted by higher seawater temperatures. Geoengineering of the climate may be the only way to save coral reefs from mass bleaching, according to new research....

Estuaries protect Dungeness crabs from deadly parasites

This item was filled under Climate
Parasitic worms can pose a serious threat to the Dungeness crab, a commercially important fishery species found along the west coast of North America. The worms are thought to have caused or contributed to the crash of the crab fishery of central California during the last half century. New research shows that infected crabs can rid themselves of parasites by moving into the less salty water of estuaries. Low salinity kills the worms creating a parasite refuge for the crabs....

3D geological tour of the Guadalquivir basin using Google Earth

This item was filled under Climate
A research team has developed a tool that allows a 3D journey in ten sites of geological and palaeontological interest in the Guadalquivir basin (Huelva, Spain). In the virtual tour, developed with Google Earth, you can visit and explore treasures of this area, such as records of the opening of the Atlantic Ocean, using tablets and smartphones....
