A bunch of AMAs today on for World Oceans Day.

Science AMA Series: Hi! I am Jenna Jambeck PhD. of the College of Engineering at the University of Georgia, I specialize in waste management and plastic waste inputs from land into the ocean. AMA for World Oceans Day!

I am Dr. Claire Simeone of the Marine Mammal Center and I am working on the Sea Lion crisis our coasts are facing. Ask Me Anything for World Oceans Day

We're Dr. Samantha Joye, Joseph Montoya, Dana Yoerger, Liz Taylor and more! we are here to talk about the challenges faced by the ocean and in ocean exploration for World Oceans Day, AMA (Ask US Anything)!

Science AMA Series: I am Meg Chadsey, the Ocean Acidification Specialist and NOAA PMEL Liaison for Washington Sea Grant. AMA for World Oceans Day!
I recently joined the twitter thing, where I post more analysis, pics and animations: @Icy_Samuel

The linked article indicates that human impact (primarily from climate change including acidification) is already stressing large portions of the oceans; and considering how much more climate change we are already committed to , hopefully policy makers will take this matter more seriously and start taking action now.

Benjamin S. Halpern, Melanie Frazier, John Potapenko, Kenneth S. Casey, Kellee Koenig, Catherine Longo, Julia Stewart Lowndes, R. Cotton Rockwood, Elizabeth R. Selig, Kimberly A. Selkoe & Shaun Walbridge (2015), "Spatial and temporal changes in cumulative human impacts on the world’s ocean", Nature Communications, Volume: 6, Article number: 7615, doi:10.1038/ncomms8615

Abstract: "Human pressures on the ocean are thought to be increasing globally, yet we know little about their patterns of cumulative change, which pressures are most responsible for change, and which places are experiencing the greatest increases. Managers and policymakers require such information to make strategic decisions and monitor progress towards management objectives. Here we calculate and map recent change over 5 years in cumulative impacts to marine ecosystems globally from fishing, climate change, and ocean- and land-based stressors. Nearly 66% of the ocean and 77% of national jurisdictions show increased human impact, driven mostly by climate change pressures. Five percent of the ocean is heavily impacted with increasing pressures, requiring management attention. Ten percent has very low impact with decreasing pressures. Our results provide large-scale guidance about where to prioritize management efforts and affirm the importance of addressing climate change to maintain and improve the condition of marine ecosystems."
