Gulf Stream Intrusions Feed Diatom Hot Spots
Previous research suggested that the intrusion of low-nutrient Gulf Stream water into the Mid-Atlantic Bight would reduce productivity, but a new study finds that it can also lead to chlorophyll hot spots.
Seafloor Seismometers Look for Clues to North Atlantic Volcanism
Did the mantle plume that fuels Iceland’s volcanoes today cause eruptions in Ireland and Great Britain long ago? A new project investigates, while also inspiring students and recording whale songs.
Studying Arctic Fjords with Crowdsourced Science and Sailboats
A new study demonstrates the benefits of crowdsourcing science using sailboats to better understand the impact of melting sea ice in the Arctic.
A Deep Dive into Organic Carbon Distribution in Hadal Trenches
Researchers use sediment cores to study the amount and origin of sediment organic carbon in one of the least studied regions of the planet: hadal trenches.
A Comprehensive Review of Submarine Volcano Seismoacoustics
Although most of Earth’s lava erupts beneath the oceans, submarine volcanoes are comparatively understudied, but a new review of submarine volcano seismoacoustics provides a framework for future work.
Laser Flashes Shed Light on a Changing Arctic
An ongoing project in northern Alaska is using pulses of laser light to monitor anthropogenic activity, ice quakes, and marine wildlife.
Anthony Brian Watts Receives 2020 Maurice Ewing Medal
Anthony Brian Watts was awarded the 2020 Maurice Ewing Medal at the virtual AGU Fall Meeting in December. The medal is for “significant original contributions to the ocean sciences.”
Scientists Mine 16th Century Ship Logs for Geophysical Research
Compass measurements held a key to unlocking the mystery of Earth’s magnetic field and its changes over time. A historian-turned-geoscientist found the measurements in an unlikely place—merchant ship logs.
Marine Isotope Stage 6: First High-Resolution Field Record
A 200-year resolution record from the Black Sea for marine isotope stage 6 (130-180 ka) shows a stable geomagnetic field.
