18 September Research Cruise

The water sampling team worked the early AM hours processing water from deep CTD casts at NH-55. We continued to enjoy calm seas as we worked inshore along the Newport Hydrographic line, completing stations NH-45 and NH-35 before water sampling and primary production experiments at NH-20. Following NH-20, we did CTDs at NH-25, NH-15, NH-10, NH-5, and NH-3. In addition to the samples from NH-20, water samples were obtained at NH-10 and NH-3.

Our track along the NH line crossed the cool filament that has extended offshore during the past week, with greater than 2 degree C surface temperature gradients at the boundaries

Following the NH line sampling, we moved north to the inshore end of the Cascade Head (CH) line and sampled CH-2, CH-5, and CH-10. The Cape Meares (CM) line followed, with CTDs through the evening at CM-1, CM-3, CM-5, and CM-10. While there was intermittent overcast during the day, we enjoyed good views of the Oregon coast as we sampled the inshore stations along these transects.
