This is still on the abyssal plain between the Kermadec Ridge and Kermadec Trench, but is starting to become a steeper slope as depths drop away towards the Trench. The hadal lander was the first aboard, and with it came video footage of a rough and rocky seafloor. Unfortunately the camera power failed after just two hours, and in that time very few fish were seen. The abyssal lander however, worked well and showed rattails, cusk eels, and large penaid shrimps-although none appeared abundant. The fish trap caught only a single fish, but there was no disappointment as it was another new record for the New Zealand region, believed to be Coryphaenoides yaquinae . There was also a good catch of amphipods. [More] Add to digg Add to StumbleUpon Add to Reddit Add to Facebook Add to del.icio.us Email this Article
