  1. Environmental Monitors on Lobster Traps

  2. Points to be highlighted today • Temperature: fixed sites over multiple years still primary eMOLT objective

  3. Points to be highlighted today • Temperature: fixed sites over multiple years still primary eMOLT objective • Salinity: now limited to investigating submarine freshwater discharge hypothesis

  4. Points to be highlighted today • Temperature: fixed sites over multiple years still primary eMOLT objective • Salinity: now limited to investigation of possible submarine freshwater discharge • Current: drift will be measured with near-surface drifters beginning June 2004 for purposes of validating numerical model simulations

  5. eMOLT database stats • # fixed sites documented: 159 • # temperature records: 1,015,591 • # salinity records: 70,170 • # drifter sightings reported: 55 • # drifter automated fixes: 15,407 • # people returning data: 104

  6. Can we explain particular events?

  7. Combining GoMOOS series w/eMOLT to look at events

  8. eMOLT Phase II: Salinity 2002 2003

  9. Can we start to correlate temperature & lobster hauls?

  10. eMOLT Phase IV: Drifters

  11. Mariners phone in: a) 5-digit ID# and b) lat/lon or loran Tollfree # on backside of pipe

  12. Summary • Temperature • springs 2003 & 2004 ~5 degF colder than 2002 • to be maintained for years to come • Salinity • redesigned to investigate “submarine freshwater discharges” in Casco Bay • Drift • summer 2003 demonstrates feasibility • summer 2004 monthly deployments planned

  13. eMOLT drifter-reporting IVR phone prompts as currently proposed: • "..... Press 5 to report a drifter sighting" • "Thank you for helping us in our study of lobster larvae drift. There are 4 to 5 prompts that follow, each expecting a keypad response. Please have the drifter’s ID# and its location ready. If anything goes wrong or is confusing , don't worry, there are other options near the end of the message. We appreciate your effort. Let's get started. Please enter the 5-digit drifter id number now:(if the user does not respond right away, the prompt will repeat itself but one can enter the 5-digit code anytime during the message)“ • "Press 1 to enter location in loran coordinates or press 2 to enter location in latitude and longitude:" • 1 • "enter the first five digits of the first loran coordinate" • "enter the first five digits of the second loran coordinate" • 2 • "enter your latitude in degrees-minutes to the nearest minute" • "enter your longitude in degrees-minutes to the nearest minute" • “Enter the day of the month the drifter was sighted followed by the # sign." • "Thank you. If you wish to be contacted, enter your ten digit phone number beginning with the area code. Otherwise, press #" • "If you have any comments, press 1 to enter a voice phone message. Otherwise, press #." • "Thank you for cooperation. If you have any questions, call 207-985-8088. That number again is 207-985-8088. Good Bye." • Note: The automated system is currently on-line at a toll free number 1-888-284-4904. The more people that try this NOW and provide suggestions, the better it will be in the end. Some of the proposed wording has not yet been implemented.

  14. Stenciled text to go on drifter sails: Sail #1: "If found adrift, take the following steps: 1) note drifter id# & lat/lon. 2) call 1-888-284-4904 3) enter "5" at first prompt, 4) follow instructions, and 5) return drifter to water. If found either ashore or SE of Stellwagen Bank, call 1-508-495-2211 and take drifter home." Sail #2: "By following instructions, you will be helping us, the Gulf of Maine Lobster Foundation, MLA, DELA, Southern Maine Community College marine science students and NOAA in a collaborative research study of lobster larvae drift. Funded by the Northeast Consortium" Sail #3: "This unit# was deployed off on by lobsterman " Sail #4: "For more information, visit 'Environmental Monitors on Lobster Traps' website at www.emolt.org."

  15. ID code convection: • Each drifter has a 5-digit ID# "ABCDE" painted on the PVC, the flag, the flotation, and subsurface sails as follows: • "A" is the year of deployment (3,4,5...) • "B" is the month of deployment (5,6,7,8, or 9) • "C" is the last digit of the deg latitude of release for the offshore-most drifter in the transect (2,3, or 4) • "D" is the last digit of the degrees longitude of releasing offshore-most drifter in the transect (0,9,8, or 7) • "E" is the offshore extent (inshoremost drifter is #1) where: • Examples: • drifter #46204 is a dark blue drifter deployed in about 40 meters of water off Glouchester Mass (~42 deg north,~70+ deg west,~) in June of 2004 • drifter #65472 is the 2nd drifter from the coast (~20m), painted black, that was deployed off Cutler Me (~44 deg north, ~67+deg west) in May 2006
