Our research cruise is being conducted this year from the Coast Guard Cutter Healy, the newest and most technologically advanced icebreaker in the U.S. fleet.  The Healy was built down around the humid bayous of New Orleans, but was designed to conquer Arctic sea ice.  The boat is a behemoth at 420 feet long and has made its way to the North Pole on several occasions, taking thousands of scientists into the Arctic to collect data that has transformed our understanding of the region.

In a common garden at the University of Rhode Island, Laura Meyerson has been growing specimens of Phragmites – also known as the common reed – that she has collected from around the world. And while they are all the same species, each plant lineage exhibits unique traits.

Now Meyerson, a professor of natural resources sciences, and Northeastern University Professor Jennifer Bowen have revealed that even when two different lineages grow side-by-side in the same ecosystem, the bacterial communities in the soil differ dramatically. It’s a discovery that will aid in understanding how plant invasions succeed and the conditions necessary for their success.

The dramatic, worldwide loss of biodiversity is one of today's greatest environmental problems. The loss of species diversity affects important ecosystems on which humans depend. Previous research predominantly addressed short-term effects of biodiversity in small experimental plots planted with few randomly selected plant species. These studies have shown that species-poor plant assemblages function less well and produce less biomass than species rich systems.

Scientists have discovered “massive impacts” on marine life in the Antarctic Ocean when waters are warmed by 1 degree Celsius, including a doubling in growth of some species and a drop in overall biodiversity, according to a new study in the journal Current Biology.

In June 2017, three critically endangered North Atlantic right whale carcasses were spotted floating in the Gulf of St. Lawrence. In the weeks that followed the number of dead right whales rose to 10, while three more were found entangled alive in fishing gear. (The total number of deaths may be as high as 12.)

For a species with approximately 500 surviving animals in the world, this was a crisis — an unprecedented die-off signalling a troubled outlook for the species.

A team of scientists from ASU’s School of Molecular Sciences and Pennsylvania State University has taken us a step closer to unlocking the secrets of photosynthesis, and possibly to cleaner fuels.

On Aug. 29, NOAA announced 15 new marine debris projects that will support marine debris removal and research received nearly $2.2 million in fiscal year 2017 funding through the NOAA Marine Debris Program. These projects support efforts to address the pervasive global problem of marine debris that can impact wildlife, navigation safety, human health, and the economy. Shown here: In an earlier NOAA-funded project, derelict fishing gear and other large marine debris were removed from remote Alaskan shorelines by the Gulf of Alaska Keeper.

Officials at collegiate sporting venues have been leading efforts toward zero-waste events with many professional and collegiate leagues adopting energy and water conservation efforts as well as increased recycling and composting. Researchers at the University of Missouri recently published a study analyzing waste and recyclables during Mizzou’s 2014 home football season. By implementing several recommendations the team developed, such as offering better recycling receptacles and better sorting options for waste, sporting venues could be well on their way to achieving environmental benefits that exceed the standards for ‘zero-waste’ operations.

Human antidepressants are building up in the brains of bass, walleye and several other fish common to the Great Lakes region, scientists say.

Ocean acidification can be a daunting topic to cover in the classroom, but for Washington state’s coastal communities, the issue is often personal.

Ocean acidification can be a daunting topic to cover in the classroom, but for Washington state’s coastal communities, the issue is often personal. In 2005, billions of oysters died along the Northwest coast, and NOAA scientist Richard Feeley and other North American scientists have linked this and other shellfish die-offs deaths to falling ocean pH1. According to Washington State’s Blue Ribbon Panel on Ocean Acidification, Washington’s ocean waters are specifically susceptible to ocean acidification because of coastal upwelling. This brings water that is low in pH and rich in carbon dioxide up from the deep ocean and onto the continental shelf. Ocean acidification, also exacerbated by nutrient runoff and local carbon emissions, threatens Washington’s marine environment, the state and local economies, and tribes.
