## Summary

- summer 2003:
-  demonstrated feasibility of approach
- all electronicless drifters reported at least once
- 6 of 8 satellite tracked drifters recovered
- 50% advected ashore along Maine Coast

## Summary (continued)

**summer 2003:**
-  demonstrated feasibility of approach
- all electronicless drifters reported at least once
- 6 of 8 satellite tracked drifters recovered
- 50% advected ashore along Maine Coast
**summer 2004**
-  monthly deployments planned June-Sept
- four transects  w/~four drifters each
- Cutler, Isle of Haut, Cape Small, Gloucester
- call toll free number to report sighting
- Visit emolt.org to view tracks
- Purpose
- Testing/evaluating numerical circulation models
- Can we document lobster larvae settlement processes?

## 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.**
** **

**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 SW 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 **

## 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
