Salinity as an Abiotic Factor at Race Rocks

			Race Rocks mean monthly Salinity Data 1935 to present This is a file with the daily sea temperatures, salinities and atmospheric data as recorded by Mike Slater at Race Rocks. Jeremias tests the salinity using a hydrometer. This manual method has been used at Race Rocks since 1935. In the video below, he and other students on one project week spent on the island prepared this summary of the daily duties: Organisms which live in Tidepools have to withstand changing salinities which may range from 0 parts per thousand to over 100 parts per thousand. Here is an example of an algae that in the summer lives in concentrated brine of the evaporated tidepool number 7. Rob measures salinity with the salinometer in tidepool Number 4..This file shows the results that one class in environmental systems got when measuring the salinities of tidepools. Note there can be quite a variation in both temperature and salinity, depending on the elevation of the pool and therefore the frequency of flooding from the ocean. Two decades of mean monthly Salinity records are compared in this investigation. A self-cleaning Sonde 6600 YSI Salinity sensor.has been installed. This file shows images of the Sonde and the various sensors, and has links to the Sonde Live Data page.
