Station M long-term time series

The Station M study is one of the most detailed investigations of any abyssal area in the world ocean. Over this 25-year study, we have continuously monitored the amount of sinking particulate matter through the benthic boundary layer.

Monitoring instrumentation suite

We use a suite of instruments, most of which are autonomous, to perform long time-series monitoring of the sea floor at Station M, off shore of the California Coast (34.5°N, 123° W).

Sargasso Sea research

Sargassum macroalgal rafts in the Sargasso Sea are vital feeding and spawning grounds for pelagic fishes, seabirds, sea turtles and whales. How might changes in ocean conditions and Sargassum habitat impact rafting animals?
