Weekend #Plankton Factoid 🦠🦐
Mating by copepods is a complicated process since they are always at risk of predation by other plankton or fishes. Male #copepods carefully mechanically and chemically track a receptive female, capture them, and deposit an adhesive spermatophore near the genital open…

Ended up with a little over 10 lbs of Asian plums from our plum tree which I hope will make some lovely jelly this fall.

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…

Small Currents, Big Impact: Satellite Breakthrough Reveals Hidden Ocean Forces
Texas A&M's Jinbo Wang and an international team use SWOT satellite data to uncover powerful submesoscale eddies, reshaping our understanding of ocean-climate dynamics.
