Dive #502 - Dolphin Beach - 28 August 2021 - Sea Cucumber Mortality Event

There's a sea cucumber (Apostichopus californicus) mass mortality event happening in Nanoose. My buddy Jill and I dove at Dolphin Beach this morning, and every cucumber we found above 30m was dead or dying. Temp was 17c in the shallows, 10c at 30m. Divers around the corner at Tyee report the same thing, as of two days ago. For our second dive, we went to Wall Beach and while there was some evidence of the same type of cucumber dead, there was less and all cukes under 14m appeared healthy. Temp in the shallows was 17c, under 15m was 10c.
