Science Activities | |
Mooring Recovery and Deployment Doug Nowacek (Duke) Sci Party Size: 5 People Retrieval and potential redeployment of a deep water mooring (HARP) off Cape Hatteras. Location: 35° 20.535 N, 74° 51.430 W We will be bringing a 70 kHz Simrad EK-60 system that will need to be temporarily deployed over the side for verification exercises. 1. Survey site for appropriate location 2. drop mooring, with pause to verify operation of the active acoustic devices 3. short echo sounder survey over the mooring location to: i) obtain simultaneous measurements from surface and mooring; ii) verify operation of the new echo sounder system being deployed. CTD and Scientific Seawater System Tammi Richardson (USC) Sci Party Size: 3 People Targeting cryptophyte populations for collection and preservation and would also be taking samples for pigment analyses. Here are the details: 1. Equipment - CTD (including fluorometer and PAR meter if available) and Niskin bottles for water collection; Use of the ship's flowing seawater (to run through an ALFA spectral fluorometer) for continuous sampling, use of a winch for doing profiles of spectral irradiance (I have a spectral radiometer, it just needs to be deployed). We'd need lab space for filtering water and for the ALFA (it's small). Spectral Radiometer to bee lowered. This is usually hand deployed, but may need to be rigged on a crane or boom to lower away from the ship's hull. Argo Float Deployment Pelle Robbins (WHOI) Sci Party Size: 1 Person Deployments are quite simple (see photo below). The individual floats are packaged in biodegradable boxes which are simply lowered into the ocean. The boxes weigh 60 lbs and each deployment requires 2 people and about 15 minutes. We would not plan to send anyone of the cruise, though we possibly could if needed. Our dates are flexible. We don't have a specific location to go to but our goal is to maintain relatively uniform coverage in the Western North Atlantic. We would adapt to whatever cruise tracks other scientists request. Our only requirement is to deploy in waters of at least 2000m depth. We would plan to deploy 4-10 floats, depending on where the ship will be headed. I've enclosed a map of the current float coverage below - yellow regions are areas which have the highest priority for more floats - however since the floats drift with the currents the distribution is always changing and will look different by spring of 2016. | |
