HARP (High-frequency Acoustic Recording Package) deployment: 06:00

Ali Bayless leads this early morning deployment of the HARP, or High-frequency Acoustic Recording Package. This is an instrument that monitors marine mammals and studies ambient ocean noise over long periods of time. Peruse the cruise course map above to find the red circle with H1. This is where the HARP was deployed. We will pick up another HARP in the location marked H2 later during the cruise. The H1 HARP will be at the bottom of the ocean for a whole year recording all acoustics in the vicinity. We are listening for various species of cetaceans in order to determine their presence near this unique oceanographic feature, the Jaggar Seamount. This is a first because a HARP has never been dropped in the area. Sixteen discs of data will ultimately provide a snap shot of what has been happening acoustically in the area. Unfortunately, we can’t take a sneak peak at the data prior to the HARP’s retrieval.

Marine Mammal Observation (MMO) training by Ali: 08:00

Ali is also our Marine Mammals Operations lead. While on the flying bridge, Ali encourages our team to keep an eye out for sperm and pilot whales. Each MMO participant will serve 45 minutes on portside and 45 minutes on starboard side in rotating shifts. We must be sure to complete the sighting form to ensure we keep track of our mammal friends. Ali provides illustrations for our team and points out a few key features of marine mammals so that we can more effectively identify them.

MMO begins: 09:30

Scientists rotate through the flying bridge throughout the day with handy binoculars. When we see a mammal, we radio acoustics to let them know the location. This is more fun than it sounds. Ocean + binoculars + flying bridge = awesome!

Science Party Interview with Aimee Hoover

Official title: JIMAR Research Data Specialist

Aimee Hoover

Aimee Hoover at the acoustics monitoring station

Aimee has spent the past two and a half years with JIMAR (Joint Institute for Marine and Atmospheric Research). She is technically a State of Hawaii employee who often has the opportunity to work with NOAA.

Her job is flexible. She can analyze data on a variety of projects. In addition to our IEA, Aimee has worked with swordfish and tuna long line fisheries, species composition, and the size and structure of animals. She frequently examines large oceanographic features such as transition zone chlorophyll front (TZCF). She analyzes the movements and the locations of the TZCF, which travel from the north to the south. She mentions that turtles often feed off of this mysterious matter.

Aimee’s favorite job task: Cruises.

On this cruise, Aimee is hoping to find: Squid in the acoustics.

Coolest thing Amy has ever seen at sea:  In Maui, Aimee witnessed a female humpback riding next to and under their ship to avoid potentially mating males. This lasted for two hours!

Personal Log

My first days on board have been a whirlwind. Our push off time was delayed by six hours. Despite this, the NOAA crew was sure to use every moment of our delay wisely. We practiced our abandon ship drill and fire drill in addition to receiving a ship safety and etiquette briefing by OPS Officer, Ryan Wattam. It looks like my muster point during emergencies is on the Texas deck, port side. There is so much to learn and so much to do aboard the Sette. I have eaten great food, visited the bridge, assisted with a CTD deployment, and have met countless amazing crew members and scientists. It is only day two!

Did You Know?

What is the difference between a rope and a line? “A line is a rope with a purpose,” according to Mills Dunlap, NOAA crew member.

A Tasty Surprise

Lines were immediately cast once underway. During an intense moment, Mills Dunlap ran toward a starboard line off the stern of the ship. Excitingly, an Ono would serve as our first catch. An omen? I think so. The food aboard the Sette is delicious!
