GLY 3074- The Oceans and Climate Change Deep Water Lab Name: Due Feb. 18 The purpose of this exercise is to give you a sense of how much variability there is from the “typical” profiles of temperature, salinity, and density that we’ve viewed in class. In additional, you will get a sense of how water masses are identified and tracked through the oceans. You will be working with 2 datasets: 1) NOAA’s EPIC site (http://www.epic.noaa.gov/epic/ewb/) This site contains the CTD (“conductivity, temperature, depth”) cast data from numerous research cruises. 2) The NOAA Live Access database ( http://ferret.pmel.noaa.gov/LAS/list-of-operational- servers ) You’ve already worked with maps from this site for the surface circulation exercise. This time you will use it to build cross sections through the ocean. In the past some students have had difficulty accessing one or both of these sites (you should be able to do so in the computer labs if it doesn’t work on your home computer); therefore, I’ve posted many of the profiles and cross-sections you will need to answer the questions on the class website under “assignment/exercise material”. I have also provided all the information you will need to create the images yourself. You’ve already worked with the Live Access site, so it’s fine if you just want to pull the plots off the class site. I’d like you to see what’s available on the EPIC site, so have asked you to download a few profiles. Although most of the material you need to answer the questions is available on the class site, you might want to play around with making cross section on the NOAA Live Access site. Part A. NOAA EPIC Database For this part of the lab you will work with several profiles of temperature, salinity, and density for locations around the ocean. Directions for working with the database
