Sunny and cool at the wharf this morning. The net tow was still mostly detritus/debris, but phytoplankton biomass increased dramatically this week. Assemblage was mostly diatoms, led by Skeletonema. Pseudo-nitzschia were seriata-size and the chains were longer. P. australis counts increased two orders of magnitude this week, while P. multiseries decreased.
