These are some really cool 1946 plankton data sampled aboard the "Pearl Harbor". The plankton were sampled using a high speed plankton sampler (no exact name provided). The torpedo-like net was towed as 9 knots at the surface (0 - 10 meters). The net has a 2.5 centimeter mouth diameter with 56xxx bolting silk. The documentation stated this mesh was 0.3 millimeters when "new" and 0.2 millimeters after use. A mesh of 233 um was assigned within the database.
