Weekend #Plankton Factoid 🦠🦐
The new Surface Water and Ocean Topography (SWOT) satellite is crazy accurate. It can measure ocean altimetry to a mm, imaging internal waves and small sub eddies (rotating mixing zones). Tiny changes in height happen when water swirls (try it in a sink) with greater height at the edges due to centripetal force. These may be even more important for temperature &a…

3D tracking of Plankton with single-camera stereoscopy
We introduce a device developed to perform a 3D tracking of passive or active particles under flow, confined in a medium of hundreds micrometers wide. Micro-objects are placed inside a vertical glass capillary and two mirrors are set behind it with a certain angle, making it possible to have the two reflections of the capillary on the same optical plane. A 3D reconstruction of the trajectories, captured with a single camera, is carried out along the vertical axis with a micrometer-scale precisi…

Marine robots are exploring the ocean's role in climate control
A robotic fleet in the Labrador Sea is tracking sinking carbon to reveal how the deep ocean helps regulate Earth’s climate.

Light is an extremely important factor in the oceans. It governs not only photosynthesis, but is also an important cue for vertically migrating zooplankton and needed for visual predation. The finding that 20% of the #oceans, especially at vital polar regions, are incre…
