Bowhead whales and plankton teleconnections

Disko Bay, West Greenland is at the end of oceanic “rivers” of Calanus copepods (red/orange lines below) that enter the bay in winter, still in diapause. They form a really dense, deep layer, and bowhead whales come from a wide area (purple) to eat them. So how much of the Calanus standing stock do the … Read more

Connectivity among rivers and subbasins of Puget Sound

Compared with most large, temperate estuaries, the biogeochemistry of Puget Sound is highly marine dominated: 70% of dissolved nutrients come from the Pacific. Nevertheless, there’s significant policy and management interest in understanding watershed contributions of environmental stressors, e.g. nutrient loading in relation to hypoxia, and pathogen and pollutant impacts on commercial, recreational, and tribal shellfish … Read more

flowWeaver: Visualizing the circulation of the Pacific Northwest coast

flowWeaver is an interactive tool for exploring transport and connectivity patterns in high-resolution ocean models such as ROMS. The initial application (version 0.4.3) contains two weeks of Salish Sea and Pacific Northwest coastal circulation during summer 2005. The underlying ocean model is MoSSea (Modeling the Salish Sea). Pablo Otero has adapted flowWeaver for an operational … Read more
