Pictured below is the chart produced by Terrafin Satellite Imaging service that I used to guide me in making decisions as to where to go to find seabirds on the August 3, 2012 Shearwater Journeys' Monterey Bay pelagic trip. Terrafin uses NOAA Polar Orbiting satellites to collect data and produce many charts for the West and East Coasts, Sea of Cortez, Hawaii, Mexico and more. Satellites cannot produce images through clouds or fog. So, the white areas, below represent fogged in areas. It is easy to see where the warm and cold water bodies meet. Look at the Davidson Seamount in the lower portion of the chart! It is hot! And, check out that curlycue swirl of cold, blue water. Terrafin even allows users to plot points on the chart and print the charts out. These are mostly used by anglers and divers. However, I began using Terrafin during the Cook's Petrel invasion, 2009. Now, I won't say exactly how I use these charts— have to keep a little bit of mystery! — Debi Shearwater for the seabirds.
