Report Details
At North Cove, sand had been removed exposing cobble stones at foot of headland. Invasive Ice Plants were found on the headland of North Cove and on the South Cove near Crook Point. Postelsia and Neurocystis in driftline. Porphyra and Mastocarpus growing on the rocks. Aggregating and Green Anemones on intertidal rocks. Large number of barnacle scars on the rocks indicting a mortality event. Water temperature was 51.9 degrees F., windspeed: 17.5 mph from Southwest. A very heavy driftline on the south beach consisting of a large amount of terrestrial debris (leaves, small woody pieces and Myrtle seeds) and the algae: Lessoniopsis, Postelsia, Egregia, Pterygophora, Nerocystis, Cryptopleura, Callophyllis, Constantinea, Desmarestia, Hymenena, Ahnfeltiopsis, Corallina, Serraticardia, and Arthrocardia. Small amounts of Gumboot Chitons, tunicates and Hydrozoa in driftline. Three Killdeer on beach. Harbor Seals swimming in the bay. Sea Stars (Piaster ochraceus) on rocks. Beach slope of 6 degrees. About 3 feet of sand removed exposing large cobbles at base of headland. Low human impact (0), but tracks of a person with a dog was observed.
