Sue Howard put together a team of ten to work at North Hastie Lake on June 14th. In past years, there has been a large pool of water in the mid-intertidal area on this beach. The water drains out as the team works its way down the upper beach and is dry by the time they reach that area. This year, the drainage path had accumulated so much sand, the drainage was blocked and the pool of water remained. Because of this about a quarter of the profile line and the +1 foot quadrats were under up to a foot of water. The team worked their way through the water and did their best under challenging conditions. They still made some good finds including the BB sized little brown barnacle Cthamalus dalli, moonglow anemones, and three species of encrusting sponge (breadcrumb, purple, and red). Other highlights from the day were an aggregating anemone (Anthopleura elegantissima) that appeared to be in the process of dividing, several decorator crabs, a deer seen wandering down the beach, and a small flock of oystercatchers that winged their way by. Quite a variety of seaweeds were seen including red coralline algae, Alaria marginata, and Costaria costata.

The North Hastie Lake team was not deterred by a little wind and rain on June 24th. Team captain Sue Howard put together a team of eleven and they stuck with it even after the skies opened up. With a -3.5 foot tide, the monitoring crew had a lot of beach to explore and they made some great finds. One exciting highlight was turning over a rock to discover a purple ribbon worm (Paranemertes peregrina) devouring a large polychaete. The team also encountered caprellid amphipods, quite a number of stalked jellies, and a northern clingfish (Gobiesox maeandricus). The little clingfish is well named. Its pelvic fins have adapted to form a suction cup-like disk that helps it adhere to the rocks that it takes refuge under. Several color spattered harlequin ducks were spotted riding the swells just out from the beach as the team worked.

North Hastie Lake's ten member monitoring team with Sue Howard at the helm was also at work on July 3rd. This valiant team persistently stuck it out in spite of monsoon-like conditions. North Hastie Lake is a mostly rocky beach located on the west side of Whidbey Island just north of the Coupeville area. The beach there has a diverse and fascinating community of invertebrates and seaweeds. It was the variety of algae that struck Jim Sommers. He and Charlie Seablom worked the quadrats and identified 12 species within those intensively studied sections including winged kelp (Alaria marginata), black pine (Neorhodomela larix), and green rope (Acrosiphonia). Charlie found and snapped a photo of a sea lemon (Archidoris montereyensis) extruding its egg ribbon. Along the profile line, Monem Mahmoud Abdel enjoyed seeing the large purple sea stars (Pisaster ochraceus) and Sue Howard got a close look at kelp crabs (Pugettia producta). Mother Nature seemed to have it out for Ingri Johnson; not only was the pelting rain trying to dampen her day, but a clam squirt also soaked her pants leg!
