Petersburg Indian Association found a Tardigrade in their phytoplankton sample last week! Tardigrades are commonly referred to as water bears. These microscopic animals can survive extreme conditions, including Arctic ice, space, volcanoes, and the Mariana Trench.

Last month, our partner in Wrangell observed 60+ dead mottled sea stars (Evasterias troschelii). Wrangell’s local Alaska Department of Fish and Game biologist and a few followers on Unusual Marine Life of Alaska believe the die off was caused by the extreme cold experienced during minus tides.

Petersburg Indian Association found a large amount of exposed cockles on Sandy Beach Thursday, January 16th. PIA is curious if anyone else has experienced this on beaches in Southeast.

STA staff Naomi Bargmann and Angela Hessenius investigating the changing tides of Herring Cove. To get offshore, they ventured on a paddle board into the bay, towing the plankton net along with them. In their sample, they hoped to confirm which phytoplankton were responsible for causing the dramatic change in water color. Hear what they found in this interview with @kcawradio! https://www.kcaw.org/2019/08/13/chalky-algae-shells-turn-sitka-seas-turquoise/

STA’s microscope room got a major makeover! This plankton mural, based off of an original design by Raven Shaw (@quickdrawmccaw) and made possible with the help of many dedicated interns and staff, is now a complete work of art that enshrines our love for the magnificent creature at the base of the marine food chain and brings joy to all those who spend time doing microscopy.
