Wet and Wild

Hold on to your hats! This past weekend, northwest winds were gusting as high as 35 knots. Cold temperatures also brought intermittent snow flurries and hail. It made for an interesting weekend to go beach combing!

Some Velella velella washed ashore by the stormy seas. There were a variety of sizes, with some of the larger ones (pictured) ~4 inches. And check out the oriention of those sails. We have a couple right-handed individuals (far left and far right).

Towing the Line- an article about the history of the Newport Hydrgraphic Line was published recently by Nancy Steinberg, and it is featured as the cover story for Oregon State University's Terra magazine.

Enjoy!

First Cruise of the Year

By Samantha Zeman
February 7, 2018


Winter storms and large swells prevented us from sampling in January, so we were especially eager to sample out to NH-25 this week. With minimal winds and sunny skies, we headed out for the first trip of 2018.

Ocean conditions were typical of winter, with a well-mixed water column and fresh water signal at the surface from high river runoff.

A quick scan of the NH-5 bongo net sample showed plankton dominated by Chaetognaths, smaller copepods and Calanus of various stages, and larval decapods. This is to be expected of wintertime samples- smaller copepods and lower densities.

Bottom photo: Bongo tow at NH-25. It's hard to miss the large pyrosomes surrounded by a smattering of juvenile euphausiids (look for the little black dots). Euphausiids were only seen at NH-25.

Pyrosomes, a name growing in familiarity along our coast, were numerous from NH-5 out to NH-25 (from 5 to 25 nautical miles from shore). The largest individuals were collected in our nets at the farthest offshore station and numerous individuals were spotted floating at the surface.

Unexpected catch! A pacific sea nettle collected in the bongo at NH-5. Is this a straggler from the 2017 fall blooms? Notice the other small zooplankters zooming around.
