Science and Technology Log
NOAA Ship Bell M. Shimada was built by VT Halter Marine, Inc. in Moss Point, Mississippi. The ship was commissioned on August 25, 2010 and is currently homeported at NOAA’s Marine Operations Center—Pacific in Newport, Oregon. The ship primarily studies a wide range of marine life and ocean conditions along the US West Coast, from Washington state to southern California.
The ship’s design allows for quieter operation and movement through the water, giving scientists the ability to study fish and marine mammals without significantly altering their behavior.
Bell M. Shimada conducts acoustic and trawl surveys. For acoustic studies, the ship uses a multibeam echo sounder (MBES) that projects a fan-shaped beam of sound that bounces back towards the ship. The ship’s MBES, one of only three such systems in the world, acquires data from both the water column and the seafloor. Scientists can detect fish when the boat passes over them, measuring the signal reflected by the fish to estimate their size and number. The system can also create a map and characterize the sea floor.
The ship conducts trawl sampling with a standardized, three-flange, four-seam bottom survey net equipped with a skipping rock sweep: sweeps with large rubber discs that allow the nets to be towed over rocky and uneven seabeds. Trawls sample fish biomass in a given study area. This helps scientists learn what species are in observed schools of fish and collect other biological data.
The ship’s wet lab allows scientists to sort, weigh, measure and examine fish. Data is entered directly into the ship’s scientific computer network. The Bell M. Shimada Bird and Marine Mammal Observation Stations are equipped with sensors to help researchers identify and track protected species.
Bell M. Shimada was named by a team of students from Marina High School in Monterey, California, who won a regional NOAA contest to name the ship. The ship’s namesake served in the Bureau of Fisheries and the Inter-American Tropical Tuna Commission. He was known for his contributions to the study of tropical Pacific tuna populations, which were important to the development of West Coast commercial fisheries after World War II. Bell M. Shimada’s son, Allen, is a fisheries scientist with NOAA Fisheries.
This has been an experience that I never imagined, on Thursday, August 11, when I entered the port and saw the ship in the distance, I felt a lump in my throat, it is much larger and more imposing than I imagined. The scientist in charge of the expedition, Beth Philips, welcomed me to the ship. She was extremely jovial and pleasant and gave me a tour of the ship, which let me tell you, this is a labyrinth. The crew has been excellent, all with a kind and respectful treatment towards me. On the other hand, I hope I can loosen up a bit more with everyone on the ship since I’m a bit in my head because of my English speaking.
I want to introduce you to the excellent team of scientists
In just a few days of meeting them, they have taught me a lot. They have all been patient and have explained and answered questions regarding the work they do on the high seas. Their knowledge and experiences have led me to create great admiration for them. In the next blogs you will learn more about each of them and you will see them in action!
Not Just One, But Two Puerto Ricans on the High Sea!
That’s right I’m not the only Puerto Rican on NOAA Bell M. Shimada, this is LT Erick Estela from Ciales, Puerto Rico. Erick is one of the NOAA Corps officers serving at sea, on land and in the air to support NOAA’s environmental science and management mission. Erick have been serving with NOAA Corps nine and a half years. We met in the middle of a drill and it was very exciting to know that there’s another Puerto Rican on board. Puerto Rico is proud to have Erick in such an important role within NOAA!
Before I go, I want to share some photos taken by Teacher at Sea Alumni Association Manager Britta Culbertson, who met us at Whidbey Island to wave goodbye from shore. Thank you for the beautiful photos and for all your support. Thanks also to TAS Alumni Denise Harrington for your messages of support, much appreciated!
See you in my next blogs where I will be talking about our study of hake populations and the data received from the echo sounder. I’m gone fishing, see you next time!
