People are always asking me for good referral Internet sites for Ocean and Weather. Over the years and I have compiled this list for my clients.
Ocean Seminar Participants:
There is a rich resource of free information available to all who have internet. Learning how to use and interpret this information will enhance your knowledge and understanding of how the Gulf Stream and eddies work.
1. (Interactive Marine Observations) This site allows you to interrogate the buoys to obtain buoy derived sea surface temperatures. You can also get lots of meteorological information like air temp, sea level pressure, wave height, barometric pressure, etc.
2. (Delft Ocean Current Model) This Netherlands site has an aesthetically pleasing color computer vector analysis of the north Atlantic. 1 week old, 2 week old, and 3 week old. Not entirely scientifically accurate (vectors only go as high as 2 knots. In reality, velocities can be much higher)
3. (AVHRR homepage) By far the best site on the web. High resolution, realtime, false color NOAA polar orbiting infrared satellite images covering the entire East Coast and Gulf of Mexico. Also 3 and 7 day composites available, archive available for several years.
4. (IMCS Remote Sensing Lab) Second best website (next to Johns Hopkins ), realtime false color imagery covering large areas and covering 3 degree squares, too. Also visible data and drifting buoy tracks. You can determine drifter velocities by computing distance divided by time. This is particularly useful information if the buoy is in an eddy or in the Gulf Stream.
5. (Global near realtime altimetry data viewer) This gives sea surface height from the altimetry data. Warm eddies are lighter than the surrounding water and have sea heights higher (10-50 cm) than the surrounding water. Cold eddies are heavier than the surrounding water and have depressed (10-55 cm) sea surfaces. Data is usually 4-9 days old. Eddy locations pretty good, Gulf Stream location poor.
I acquire images from each of these sites, download them, and analyze them using photoshop software. My final products are a combination of the interpretation from all the infrared imagery (black and white as well as false color).
