Following a short stop at Torshavn (Faroe Islands) last weekend for a crew swap, the FS METEOR is back in the sampling area in occassional heavy seas.

Due to a problem, 24hrs were lost from the schedule, but the team is now trying to catch up. Seniour scientist aboard, Michael St John, mentions that the surface has not yet stratified, but FS METEOR is sailing in surface bloom conditions.

“Convection is still spinning out here. Amazing!!”Marine educators willing to learn more about a Blooming Ocean, what causes a bloom, why and why researchers study the bloom in the North Atlantic, the Center for Ocean Science Excellence & Education East (Un. Maine) has prepared an online series of seminars and supporting materials (including science lesson plans for high schools).

Mary Jane PerryIntroduction to the North Atlantic Bloom by Mary Jane Perry
(Professor, School of Marine Sciences, University of Maine) gives an overview of the North Atlantic Bloom Project and describes the fundamentals of how phytoplankton bloom in the ocean.
Amala MahadevanWhat Triggers The Bloom? by Amala Mahadevan and Melissa Omand (WHOI) explain how modeling has helped researchers to better comprehend the physical dynamics behind what triggers the spring bloom.
Eric D'AsaroMeasuring the Bloom by Eric D’Asaro
(Principal Oceanographer and Professor, APL-UW) presents his perspective on how it is possible to measure a moving, changing swatch of ocean at different scales, and the technology needed to collect meaningful data.
Nicole Poulton and Ivona CetinicCarbon Cycling & the Marine Food Web by Nicole Poulton
(Bigelow Laboratory) and Ivona Cetinic (University of Maine) describing the ecological succession that happens during a phytoplankton bloom, and the consequences for the marine food web and for carbon exports.
Craig LeeBroader Implications by Craig Lee
(Principal Oceanographer and Professor, APL-UW) wraps up the series with a “big picture” summary of what understanding the dynamics of the spring bloom will mean for scientists concerned about carbon and climate.
