README for Coos Bay CTD data in matlab file: AllCTD.mat

August 14, 2015

The majority of these data come from along-estuary transects from the mouth of Coos Bay to wards the Coos River end (or Isthmus Slough). Measurements from each downcast were bin-averaged into 0.5 m bins. 

Note that if no data exists, a NaN is used. All casts should have Temp and Sal, but sometimes we did not sample for DO. The depth of the profile varied too, so many of the columns in the T,S,DO matrices are NaN's below their final depth. 

Variables in the mat file:
1) z: depth in meters (0.5:0.5:20)
2) td: matlab datenum time vector in local time (PST/PDT)
3) sal: matrix of salinity data with size n x m, where n is length(z) and m is number of profiles (402)
4) temp: same as sal but for temperature data
5) oxy: same as sal but for dissolved oxygen (taken with Rinko optical DO sensor), in mg/L
6) chl: same as sal but for chlorophyll/fluoroscence (taken with Seapoint fluormeter), in g/L
7) lat/lon: position data for each profile
