Seasonal phytoplankton blooms in the North Atlantic linked to the overwintering strategies of copepods

April 18, 2016 | Publication Highlights, Ecology and Biodiversity, Oceanography

“Seasonal phytoplankton blooms in the North Atlantic linked to the overwintering strategies of copepods,” co-authored by Nereus Fellow Rebecca Asch (Princeton University), was recently published in Elementa: Science of the Anthropocene. The paper looks at when and how long phytoplankton blooms occur in the North Atlantic. The authors found a correlation between spring bloom start days and the duration of the bloom, with early blooms lasting longer.

Temperature-based targeting in a multispecies fishery under climate change

April 7, 2016 | Publication Highlights, Climate Change, Oceanography

The paper “Temperature-based targeting in a multispecies fishery under climate change” was recently published in Fisheries Oceanography by Nereus Program Fellow Daniel Dunn (Duke University) and Principal Investigator Patrick Halpin (Duke University). The study looked at whether the bottom temperature of the water, in spring and fall, affected the distribution of Atlantic cod in the USA Northeast compared to other species of fish.

Process versus products: The role of creativity in the working lives of scientists

By Rebecca G. Asch, Senior Nereus Fellow, Princeton University

My mother is an abstract expressionist painter who creates art using oil paints, acrylics, watercolors, and pen and ink. My father has a Masters degree in physics and spent most of his career working as a software engineer. As a result, I have born witness to many conversations about the intersection between art and science throughout my life.

Investigating ideal fishing conditions for tuna and swordfish in the U.S. northwest Atlantic ocean

February 17, 2016 | Publication Highlights, Fisheries, Oceanography

Recently published in Fisheries Oceanography by Nereus Alumnus Andre Boustany (Duke University) and Principal Investigator Patrick Halpin (Duke University) was the study “Tuna and swordfish catch in the U.S. northwest Atlantic longline fishery in relation to mesoscale eddies”. This research looks at the effects of different variables on the catch of tuna and swordfish — including mesoscale eddies, which are a type of ocean current, sea surface temperature and fishing gear used.

COP21: Where have all the fish gone? How climate change is displacing marine species.

December 3, 2015 | Policy Forum, Climate Change, Oceanography

Climate change could affect temperatures all over the world, but what may not be immediately apparent is that climate change will affect ocean temperatures. If CO2 emission rates do not change, the average sea surface temperature is expected to increase by 2 to 3.5 degrees Celsius by the end of the century. This may not seem like much, but it would impact oceans in many ways, making them quite different from how they are today.

Daniel Dunn on oceanic fronts and seamount productivity in Fish and Fisheries

September 28, 2015 | Publication Highlights, Oceanography

Daniel Dunn, Nereus Senior Research Fellow in the Marine Geospatial Ecology Lab at Duke University, has published a paper on how environmental conditions and oceanic fronts promote seamount, underwater mountain, productivity. “A perspective on the importance of oceanic fronts in promoting aggregation of visitors to seamounts” (PDF) was published in Fish and Fisheries.
