Date	Time	DecLat	DecLon	Log	
10/14/01	17:03	82.51870	-13.05743	Deck testing buoy launcher section of buoy launcher section commencing.  Tests were successful, including new buoyLauncherTest utility.	
10/18/01	14:21	81.99597	-11.85525	Vehicle assembled with buoy launcher section, testing in preparation for potential operations at ice edge this evening.	
10/23/01	19:50	80.60292	-15.85877	Dunk tested vehicle with buoy launcher to see if water caused the problem with the buoy launcher to reappear.  The launcher found one real buoy 5/5, another real buoy 4/5, and the dummy buoy 5/5.	
10/23/01	17:39	80.67237	-16.48312	Doug was able to command the launcher to find a buoy through the buoy launcher test cable, and Rich was able to repeat through the MVC.	
10/23/01	17:29	80.68563	-16.49037	Vehicle back on deck after unsuccessful attempt to launch buoy.  Buoy launcher was unable to find a buoy during the BuoyRotate behavior.  Ran several successful waypoint missions including a waypoint with depth control via yoyo behavior.	
10/24/01	20:14	80.82827	-16.74222	Found problem with buoy launcher inductive comms coil -- worked much less well than hand-held test coil.  Armen intends to debug before putting buoy launcher back in water.	
10/26/01	14:38	81.60170	-18.16938	Buoy Launch Test
0907  ROV in water
0914  ROV looks for potential buoy launch location
0941  Buoy placed in water, opens and rights itself
0942  Rov grasps buoy and transports to area under ice
0949  Reaction to heat buoy nosecone has not yet occurred.
0958  Pump in buoy does not appear to be pumping.
1013  Cap pops off and antenna inflates.
1015  Argos communication confirmed.
1055 Recover Rov and buoy.

Note: Examination later in the evening indicates a stuck Lexan valve.	
10/26/01	7:52	81.13650	-15.54700	ROV in the water with live buoy in order to film burn through the ice.  Pyroclastic reaction did not seem to initiate -- leaving buoy in to test antenna inflation and ARGOS comms.	
10/28/01	19:08	81.03787	-19.23127	Buoy testing: Buoy #2 quit sending updated data, decision was made to
pull it before battery died and see what the problem is. Suspected computer
issue (locked up maybe per Doug A.). Armen retrieved buoy via the basket and deck crane. 	
10/28/01	17:27	81.05580	-19.17960	Second live buoy test from ROV.  Buoy reaction started but was unable to burn through ice beyond a few centimeters.  ARGOS antenna expanded and transmitted but no GPS fix was acquired.  Left buoy off aft port quarter of ship overnight to test ARGOS transmission endurance.	
10/30/01	14:54	80.29065	-11.32520	Test of buoy in hole drilled in floe of multi-year ice.  Buoy was armed in the launcher and then lowered into the water to cold soak and expand, before being installed in the ice hole for ARGOS transmission testing.	
11/2/01	9:23	78.79802	0.26068	Argos testing of Buoy -
Weather - wind increased from approx. 15 knots to 24
Decision to place ARGOS capable buoy in ice for transmission
testing. Hole drilled into ice for buoy placement, note - this 
approach possibly exposes batteries to colder temps than design
specificaitons.  Argos antenna inflated and then lost air -- strapped it to a wooden stake and then departed.	
11/2/01	8:59	78.80333	0.24168	Second attempt at same location to initiate melting section.
Weather the same.
Buoy melt head did not initiate again. Buoy retrieved for
analysis. 	
11/2/01	8:58	78.80360	0.24065	Another buoy attempt
Conditions fair and steady. 
Failed to initiate Pyrosolve-Z pellet, recovered buoy. 	
11/2/01	5:44	78.84355	0.07570	Preparing for under ice ROV launch of buoy with burn pellet cleaned with hydrogen peroxide.
