University of Maine scientists are part of an interdisciplinary research team equipped with advanced underwater robotics and analytical instrumentation that will set sail in August from Seattle to the northeastern Pacific Ocean.<\/p>\n

They\u2019ll examine the life and death of plankton \u2014 microscopic organisms that are the base of the ocean food web and play a key role in removing carbon dioxide from the atmosphere and oceans. The researchers seek to better understand how the planet is changing in response to the increasing amount of greenhouse gases.<\/p>\n

91¸£Àû professor emerita Mary Jane Perry, professor Emmanuel Boss, associate professor Lee Karp-Boss and oceanography doctoral candidate Nils Haentjens are participating in the project supported by NASA and the National Science Foundation called the\u00a0Export Processes in the Ocean from Remote Sensing (EXPORTS)<\/a>oceanographic campaign.<\/p>\n

Boss and Haentjens will be aboard the\u00a0Roger Revelle\u00a0<\/i>and Perry will be on the research vessel\u00a0Sally Ride<\/i>.<\/p>\n

From these seaborne laboratories, they\u2019ll examine plankton as well as the chemical and physical properties of the ocean from the surface to 3,200 feet in depth. That\u2019s called the twilight zone, a region with little to no sunlight, where carbon from plankton can be kept out of the atmosphere for decades to thousands of years.<\/p>\n

Boss and Karp-Boss, who are co-principal investigators of an Oregon State University-led portion of the project, will examine with Haentjens how phytoplankton community properties determine the movement of organic carbon from the ocean surface to the twilight zone.<\/p>\n

They\u2019ll apply the data to improve NASA\u2019s satellite measurements of carbon export.<\/p>\n

\u201cWe apply state-of-the-art imaging and optical sensors to study phytoplankton communities, building on capacities that we developed for another NASA-funded study (North Atlantic Aerosols and Marine Ecosystems Study\/NAAMES) in the North Atlantic Ocean,\u201d says Karp-Boss. \u201cNow we have the opportunity to study a contrasting system in the Pacific Ocean, so I\u2019m very excited about this opportunity.\u201d<\/p>\n

Boss says the project could yield exciting, new perspectives and that researchers could learn in ways they didn\u2019t anticipate prior to being at sea for nearly a month.<\/p>\n

The data, he says, are likely to improve models, including those in the Intergovernmental Panel on Climate Change reports. \u201cIt is hoped the public and politicians may make decisions based on these models to mitigate climate change,\u201d Boss says.<\/p>\n

Perry, the former director of the Darling Marine Center, is a co-chief scientist on the project. She\u2019s been involved with planning EXPORTS since 2014, soon after its inception.<\/p>\n

Perry\u2019s a co-principal investigator on a University of Washington-led portion of the project. \u201cMy science role is to coordinate calibration of the autonomous robots that will be deployed a month before the August cruise and that will continue to make measurements for months after the ships head home,\u201d she says.<\/p>\n
