Science and Technology Log
So Far the sea scallop survey has collected 76,170 sea scallops which can also be expressed as 9,251 kilograms. This is a tremendous amount of scallops and the survey is not even a third of the way complete. At stations where crabs and starfish were sampled we have collected 8,678 cancer crabs and 279,768 starfish (Asterias) so far. Without a reliable database like FSCS it would be impossible to keep up with such a large amount of information.
Today I got a chance to talk with Shad Mahlum. He is a seagoing technician for NOAA and was born and raised in Montana. He has experience working with freshwater surveys. In the past years he has studied how beaver dams influence native and non-native species of freshwater fish. Shad also spent some time looking at various cattle grazing strategies and how they affect food chains. Shad loves working on the open ocean and the physical process of sea scallop surveys. Shad hopes to work with freshwater and saltwater projects in the future.
As I was gazing out into the deep blue sea a very large animal caught my eye. I was so excited to see another Finback Whale. They are the second largest animal on earth after the Blue Whale. They are known to grow to more than 85 feet. Finbacks are indifferent to boats. They neither approach them nor avoid them. Finback Whales dive to depths of at least 755 feet. They can grow anywhere from 30-80 tons. Finbacks eat Krill, fish and squid and their population numbers are approximately 100,000 or more. The only threats Finbacks have are polluted waters. It is incredible to see such a large animal breaching out of the water. I will never forget it.
