March 2012 was a total disaster weather wise in the Pacific NW....wet, cold, windy day after day.  April is looking better.  The first good low tide series of spring arrived this week, with the best low on Monday 4-9-12 if minus 2.3ft.  Very low tides are ahead in early May, early June and early July.
Weather lately has seen temperatures in the high 60's with sun.....yes SUN.
The first Moon Snail egg laying was observed this weekend, as well as much egg laying going on with the Red Burrowing Sea Cucumber, one species of Bubble Shell Snail, the Graceful Cancer Crab and an unidentified species of segmented worm.  No doubt other species were spawning but not observed.
Images from this week include two species of Bubble Shell Snails...one laying eggs, Graceful Cancer Crab with eggs, spawning Burrowing Sea Cucumber, and Brant Geese (which a migrating north) feeding on green seaweed Ulva.
Seattle Aquarium Beach Naturalist training was held on Alki and Golden Garden beaches on Saturday April 7th under sunny sky with a cool north wind.
