World Oceans Day

Posted 2 months 1 week ago

Every June 8 we celebrate World Oceans Day, a day that was created to raise awareness about how we as a planet can help preserve our oceans. At Franklin College, we are fortunate to have many researchers who study our oceans and speak out. This year, the theme of the day in celebration is combating plastic pollution and our own Jenna Jambeck has a message for the United Nations on the topic. 

Plastic pollution in our oceans has been piling up for decades. Jambeck estimates that 5 million and 14 million tons of plastic ends up in the world's oceans every year, but there are some...

NASA Research on Sea Level Rise in Greenland

Posted 2 years 11 months ago

A NASA Interdisciplinary sciences project by UGA faculty lead by Thomas Mote and including Patricia Yager and Renato Castelao collected data this summer at the top of the world:

On Greenland’s ice sheet, a vast icy landscape crisscrossed by turquoise rivers and dotted with melt water lakes, a small cluster of orange camping tents popped up in late July. The camp, home for a week to a team of researchers, sat by a large, fast-flowing river. Just a kilometer downstream, the river dropped into a seemingly bottomless moulin, or sinkhole in the ice. The low rumble of the waters,...

World Oceans Day

Samantha Joye and other ECOGIG scientists participated in person and online to celebrate, and elaborate on, World Oceans Day on June 8:

World Oceans Day is the United Nations-recognized day of ocean celebration and action. People all over our blue planet organize events to support action to protect the ocean. This year, the theme is Healthy oceans, healthy planet.

ECOGIG hosted a Media and Education Day in Gulfport, Mississippi from 10 a.m. to 1:00 p.m. at the port of Gulfport. ECOGIG scientists are at the midway point in their three-and-half-week-long research cruise on...

Use of dispersants in oil spills

Posted 3 years 3 months ago

The complexity of what happened in the Deepwater Horizon/BP drilling platform explosion and resulting sea-floor oil gusher that flowed for 87 days is only dwarfed by what has happened in the time since. The clean-up, which began immediately, has been a Herculean effort that continues to this day. But a new perspective article in Nature by Samantha Joye and her colleagues brings attention to one problematic aspect of the clean-up: the use of chemical dispersants to break up the oil into small droplets that could be easily degraded by microbes. There seems to have been no definitive...

Science advances: the marine carbon cycle

Posted 3 years 7 months ago

The amount of dissolved carbon in the world's oceans is roughly equivalent, and likely greater, than atmospheric concentrations of CO2. Some of it gets semi-permanently sequestered, some gets released up into the atmospheric in a process that has been in place for millions of years. But with the global carbon picture changing, understanding the details of these processes has become more urgent: the slightest changes in ocean temperature or acidification (not hypothetical: we know these conditions are in flux) could usher in major changes in the relationship between the carbon in...
