Underwater photographers Brian Skerry, Steve De Neef and Luis Lamar, scientists Jon Witman and Fiona Beltram and Dive Safety Officers Elizabeth Kintzing and Jeff Godfrey returned late Sunday night, June 5, 2016, from the second expedition to Cashes Ledge, this time aboard the RV Connecticut.
The team photographed the luxuriant kelp forest on Ammen Rock, along with the abundant fish – cod, pollock and cunner – and myriad invertebrates living on the surface of the mountain peak and within the forest.
Jon and Liz repeated their surveys of kelp and fish populations, finding dense Saccharina kelp (see image below) growing more than 5 meters in height, reaching astounding standing stock biomasses up to 7.0 kg per square meter at 15 meters depth.
The window of good weather enabled the team to dive consecutively for 2.5 days – the longest stretch of diveable days at Cashes Ledge in recent years!
