Phytoplankton and organic matter in the oceans that floats near the surface attenuate the light entering the water, filtering the light and changing how it affects the water below. One type of material found in the oceans, known as colored detrital matter (CDM), is a mix of organic material from various sources: material formed in the ocean, washed from land

An AUV-ALR deployed by the U.K. National Oceanography Centre has completed its first under-ice Antarctic mission. The autosub long range (ALR) AUV was used as part of the British Antarctic Survey’s Filchner Ice Shelf System (FISS) Project. The AUV, which was named “Boaty McBoatface” through an internet poll held by the UK Natural Environment Research Council in 2016, was deployed

Research published in the journal Biogeosciences examines the chemistry behind an annual algal bloom and the algae that cause it ─ tiny, single-celled photosynthesizers called coccolithophores that are neither plants nor bacteria. Their microscopic swarms, shown in this NASA satellite image, dominate the Great Calcite Belt, a ring around the Southern Ocean so large it can be seen from space.

Beginning in summer 2018, twelve groups of scientists will undertake field expeditions to perform robotic sampling, optical instrumentation deployments, light scattering and more as part of a NASA project to more thoroughly understand ocean carbon flux. The project is called EXPORTS (Export Processes in the Ocean from RemoTe Sensing). Two expeditions with investigators from a wide variety of sciences will
