Deep-Sea Respiration Expedition 2018 – Log 4

Today is the last day of this research cruise. Our station is in the bay and we awoke to feeding whales surrounding the ship this morning. We will recover the MRS, put all our samples away, clean the lab, and head back to the beach. It has been a productive and interesting expedition for all the researchers, but we are looking …

Deep-Sea Respiration Expedition 2018 – Log 3

Yesterday was an early start with a goal of retrieving the MRS from the 2,000 meter mooring. During the dive, we spotted a rare deep-sea jelly, Vampyrocrossota childressi and a very full black swallower, Chiasmodon niger.

Smithsonian National Museum of Natural History Postdoctoral Fellow Chan Lin My goal here is to collect amphipods, specifically from the genera Paraphronima, Cystisoma, Streetsia, Lanceola, and Scypholanceola. Each of those hyperiids has a distinct eye type. I am interested in studying how their vision works and how their visual world is represented in the brain. This is my first ever …

Deep-Sea Respiration Expedition 2018 – Log 1

Our mission today was to fill and deploy the MRS at our deep mooring site (2,800 meters). Locating target animals is a challenge at this food-limited depth, but as the ROV flew closer to the seafloor we were able to successfully fill the chambers with a mysid shrimp, an eelpout, and several snailfishes. Respiration rates will be measured in the field over the next 48 hours, …

Deep-Sea Respiration Expedition 2018

MBARI Expedition #446 Expedition goal: The principal goal of this expedition is to measure oxygen consumption rates of select deep-sea animals using a custom-designed tool, the Midwater Respirometry System (MRS). Weather permitting we will deploy the instrument at both shallow  (approximately 300 meters) and deep (approximately 3,000 meters) depths. We will also be observing and collecting midwater animals to …
