00:28:50 - 20231026T223712Z Note:  teather_management
00:32:22 - 20231026T224044Z Note:  translucent jelly, purple hue
00:38:38 - 20231026T224700Z Note:  approaching_WP2
00:41:03 - 20231026T224925Z Note:  nar waypoint 2 there is a tallus bottom with purple urchins, anemones, small corals
00:41:58 - 20231026T225020Z Note:  atalanta having issues following heading directions
00:45:45 - 20231026T225407Z Note:  here as we near waypoint 2 there are many liponema sp. anemones. there appears to be a strong current here and some corals have began to appear
00:50:09 - 20231026T225831Z Note:  Atalanta is struggling to follow heading due to the current
00:51:28 - 20231026T225950Z Note:  correction from earlier observation, urchins were not seen, they were liponema
00:56:05 - 20231026T230427Z Note:  continuing operations after troubleshooting atalantas thrusters
01:06:30 - 20231026T231452Z Note:  waypoint_2
01:15:29 - 20231026T232351Z Note:  continuing norbit survey
01:31:56 - 20231026T234018Z Note:  using magnum arm and knife to release atalanta
01:40:43 - 20231026T234905Z Note:  magnum arm was used to pass the knife to the craft arm, the line is caught near the base of atalantas connection to the ship, atalanta has been unable to respond to heading changes and we will use the knife to release the line from around atalanta
01:45:02 - 20231026T235324Z Note:  note that coral cutters are not on the craft arm which is why a knife must be sued to release the line
01:47:43 - 20231026T235605Z Note:  re approaching atalanta from another angle to prevent tangling of teather
01:51:17 - 20231026T235939Z Note:  made contact with the line attempting to grab it with the magnumn arm
01:53:32 - 20231027T000154Z Note:  managing loops in tether then will continue to release Atalanta
