SIO 119: Physics and Chemistry of the Ocean

TIDE POOL FIELD TRIP: 2 February 2015

We carried out our annual class field trip to the the tide pools located between Scripps Pier and Blacks Beach to examine how chemical and physical properties of a tide pool evolve during the time that it is isolated from the open ocean. Cliff Hoang served as our photographer, except where noted. class picture

tide pool sampling This year we sampled 3 tide pools, testing for the temperature, salinity, nutrients, pH, and total alkalinity of the water.

We had a little difficulty with an octopus, who stole a TidBit and tried to get a Hobo Logger. (photo credit: Heather Page) tide pool sampling
