TIDE POOL FIELD TRIP: example photos from past years

When the class was smaller, we were able to take groups of students to the tide pools located between Scripps Pier and Blacks Beach to collect a several-hour-long timeseries of physical and chemical measurements. The tide pools provide a model system to examine how an isolated system evolves over time. These photos are from 2015, when Cliff Hoang served as our photographer, except where noted. Data from these measurement campaigns might show up in this large lecture class.
	In 2015, we sampled 3 tide pools, testing for the temperature, salinity, nutrients, pH, and total alkalinity of the water.
	Temperatures were measured using TidBits and Hobo Loggers, here in "tide pool 1".

	At regular intervals, we measured total alkalinity, temperature, salinity, and pH.
	Other properties of the tide pools were noted, including depth, horizontal dimensions, and types of organisms living in the pool.
	Samples were returned to the Andersson lab to be run.
