Euphausia superba length frequency from zooplankton collected with a 2-m, 700-um net towed from surface to 120 m, aboard Palmer LTER annual cruises off the coast of the Western Antarctic Peninsula, 1993 - 2024.

Euphausia superba standard lengths (SL) were measured at grid stations on the annual LTER cruises along the western Antarctic Peninsula (WAP). Annual cruises take place between late December to early February, except for the NBP21-13 cruise, which was November and December. Krill were collected with a 2x2 meter, 700um mesh net fitted with a flow meter and towed obliquely to 120m.
