    Molecular approaches and mobile sampling platforms unravel diversity of Pseudo-nitzschia in Monterey Bay

    During 2015, the west coast experienced one of the most extensive toxic blooms on record for the harmful marine diatom Pseudo-nitzschia. In Monterey Bay, moderate intermittent upwelling supplied the nutrients needed for cell growth and accumulation during relaxation periods. The increased biomass exhausted the available silicate required for growth, which in turn contributed to high toxin production. Unprecedented domoic acid levels led to widespread closures of commercial and recreational shellfish and finfish harvests. A multidisciplinary network of platforms (stationary and mobile) and molecular technologies (traditional and advanced) was used to measure temporal and spatial patterns of Pseudo-nitzschia and toxicity throughout Monterey Bay during this coast-wide event. This approach provided for high-resolution sampling that captured a shift to P. australis as the dominant species in early spring preceding the bloom, while subsequent time series data recorded consistently higher cell abundances for this species and record-breaking toxicity in the south bay. While this event was one of the most intense on record for Monterey Bay, Pseudo-nitzschia have been a part of the phytoplankton community for decades and yearly blooms with varying intensities are now a regular occurrence. New tools are providing unique opportunities to study population fluxes within the water column as we continue to search for connections with oceanic and anthropogenic influences.

    What controls distribution of particulate trace elements in the Eastern Tropical South Pacific Ocean?

    Particles play an important role in the cycling of many trace elements (e.g., Fe, Mn) in the ocean by scavenging and transporting the trace elements to the deep sea. As their settling speed and interaction rates, e.g. scavenging, remineraliztion, and (dis)aggregation, depend in part on particle size, it is essential to understand the distribution of trace elements between small (suspended) vs. large (sinking) particles and its controlling factors. Here we will show size-distribution of particulate trace elements data from the Eastern Tropical South Pacific collected during the U.S. GEOTRACES GP16 cruise, and discuss the potential processes that control the cycling of particles and associated trace elements in various environments, including hydrothermal vent system.
