During this first leg of the Southern Expedition, we will be conducting respiration index experiments on marine organisms in the Santa Barbara Basin. The objective is to learn more about the oxygen levels in the water and where marine organisms live in relation to those levels. We will be collecting water samples to measure oxygen, temperature, and salinity levels. We will also be conducting laser Raman studies of pore-water chemistry in the sediments on an asphalt volcano in the Santa Barbara Basin and at active methane gas venting sites and seafloor mounds in the Santa Monica basin. Our laser Raman spectrometer bounces a specially tuned laser beam off of almost any object or substance—solid, liquid, or gas—providing information about that object's chemical composition and molecular structure. This is a much better method for measuring the chemistry of the water in the sediments than collecting a push core, which requires bringing the sediments to the surface, squeezing out the water and then analyzing the chemistry. We will also be conducting preliminary exploratory observations of the seafloor inside the Santa Cruz basin.

The main objective for this leg of the cruise is to deploy the Deep Sea Environmental Sample Processor (D-ESP). Two days will be spent on/near the Southern California Methane Mound, and two days will be 'off' the mound, yet nearby. We will also recover McStar (on mound) and the nearby Nobska CTD frame. We also will collect water with both the ROV and large CTD rosette for biogeochemical analysis, and we hope to collect several push-cores.
