Eyes on a dynamic ocean
In rain or shine, often under dark skies, Newport Line scientists have been heading out to sea twice a month to sample the waters off Newport, Oregon. This unique oceanographic time series has been in motion for 25 years. That’s a lot of sea days! We use the water and plankton samples collected on the Newport Hydrographic Line (NHL) to characterize ocean conditions and food web structure in the Pacific Northwest.
Plankton, the tiny drifters of the sea, form the basis of the marine food web and are links to higher trophic levels, like PNW fisheries, whales and seabirds. By quantifying zooplankton samples, we can describe the health of marine ecosystem and forecast salmon returns, rockfish recruitment, green crabs, and marbled murrelet success, just to name a few examples. Our ability to sample bi-monthly allows for fine-scale ocean monitoring that is only becoming more important in a changing climate. We are the eyes on the water!
