New vulnerability assessment to help guide fisheries management
Rapidly warming ocean temperatures off the coast of the Northeastern U.S. are likely to have a big impact on nearly all fish and other marine life in the region. Scientists with the National Oceanic and Atmospheric Administration carefully surveyed 82 species in a recent study, trying to identify which are the most vulnerable to global warming.
“Our method identifies specific attributes that influence marine fish and invertebrate resilience to the effects of a warming ocean and characterizes risks posed to individual species,” said Jon Hare, a fisheries oceanographer at NOAA Fisheries’ Northeast Fisheries Science Center (NEFSC) and lead author of the study. “This work will help us better account for the effects of warming waters on our fishery species in stock assessments and when developing fishery management measures.” Continue reading

New protection to aid recovery of rare marine mammals
North Atlantic right whales will have a little more protection off the East Coast, as NOAA’s National Marine Fisheries Service expanded critical habitat to cover feeding areas in the Gulf of Maine/Georges Bank region and southeast calving grounds from North Carolina to Florida.
The expansion does not include any new restrictions or management measures for commercial fishing operations, but it would require more extensive review of any proposed activities in the region. Continue reading

In just 15 years, renewable energy could power most of the U.S. @bberwyn photo.
Huge cuts in greenhouse emissions possible by 2030
Germany’s deliberate transition to renewable energy — the Energiewende — has made headlines around the world, but the U.S. also has the potential to make a big shift toward renewable energy.
Solar, wind and other weather-driven renewable resources could supply most of the nation’s electricity by 2030 and potentially cut greenhouse gas emissions from the power sector by up to 78 percent, according to a new study by researchers with the National Oceanic and Atmospheric Administration and the University of Colorado.

Experts say no sign of slowdown in long-term warming trend
2015’s global average temperature broke the record by the biggest margin ever, and 2016 could be even warmer.
By Bob Berwyn
The average global temperature for 2015 was the warmest since record-keeping started in 1880, breaking the mark set last year by a full quarter degree, according to the latest climate update from NASA and NOAA.
Discussing the new temperature record in a telephone conference call, experts with the two agencies said 2016 could be hotter yet because of warmth stored in the oceans. There’s no sign at all that the long term global warming trend will slow down any time soon, said NASA researcher Gavin Schmidt. Continue reading

The Arctic continues to warm much faster than the rest of the planet, according to NOAA’s annual Arctic report card.
Scientists track fish populations, ice extent and river discharge
Temperatures across the Arctic were the warmest on record in 2015, ranging more than 2 degrees Fahrenheit above average, according to the National Oceanic and Atmospheric Administration’s annual Arctic report card.
Released earlier this month, the report showed documents increasing air and sea surface temperatures, decreasing sea ice extent and Greenland ice sheet mass, and changing behavior of fish and walrus in the region.
The report card is a “key tool” to understanding how the changes will affect communities, businesses, and people around the world,” according NOAA Chief Scientist Dr. Rick Spinrad. Continue reading

Impacts of oil pollution expected to affect Barataria Bay populations for a long time

There’s already a wealth of research showing that the Deepwater Horizon oil disaster in the Gulf of Mexico was very bad for coastal dolphins. One study, for example, showed dolphins in Barataria Bay exposed to BP’s oil suffered lung disease and hormone deficiencies.
In a report released this week, a team of researchers led by National Ocean and Atmospheric Administration scientists is reporting a high rate of reproductive failure in dolphins exposed to the 2010 spill. The biologists monitored bottlenose dolphins in heavily-oiled Barataria Bay for five years following the spill. Continue reading

Coho salmon are struggling, but a new report suggests that boosting stormwater treatment could help them in some environments. Photo courtesy USGS.
Green stormwater infrastructure needed to protect salmon in urban streams
Simple sand and soil filters could prevent much of the pollution from urban runoff that’s killing adult coho salmon in West Coast streams, NOAA researchers found after studying water quality around Puget Sound.
The research traced the link between toxic parking lot runoff and other urban pollution and salmon deaths. More than half the coho salmon returning to urban streams dominated by stormwater runoff die every year before they spawn. Continue reading
