Science Objectives | |
This mission involves the collection of physical, biological and chemical oceanographic data onboard oceanographic surveys conducted in 3 different geographic regions: Gulf of Maine and Scotian Shelf and Slope (Maritimes Region AZMP, AZOMP), Newfoundland and Labrador Shelf (Newfoundland and Labrador Region AZMP), and in the Labrador Sea from the Labrador Shelf, Canada to Cape Desolation on the Greenland shelf (AZOMP). Through the collection of an array of physical, chemical, and biological oceanographic data, this mission aims to:

This field work involves the deployment of various tethered and non-tethered oceanographic equipment for the collection of physical, chemical, and biological oceanographic data. Specific objectives of the field work that will be conducted on each of the 3 legs of this mission includes: Leg 1 – MAR AZMP: Embark: Halifax, Nova Scotia.

Storage Notes: We require 3 ultra-cold (-70) and -20 freezer space for sample storage, as well as ample refrigeration space. Use of the ship's deionized water system will be required for the production of ~400 litres of deionized water. The ship's nitrogen system will also be used for the production of liquid nitrogen, that will be used to top up several liquid nitrogen dewars at regular intervals. | |||||||||||

Navigation Notes: We require access to NMEA data throughout the mission. Are these data available as a string through ethernet, or serial cable (RS232 or RS422/485)? The NMEA string is fed into our Event Logger (E-LOG), and is also required by our TSG logging computer (if applicable), XBT system and mooring deployments. The NMEA string should have GPS position, time and sounder (sddbk/sddbt/sddpt, GPZDA and GPGGA). Does the vessel have computers situated in work areas that contain navigational software where we can track ship's position and time to next station? | |||||||||||

Winch Notes:
For Legs 1 and 3, vertical ring net tows will be conducted using the hydro winch with 0.25 inch hydrowire. This system consists of a 4 m net with 0.75 m opening and 202 micron mesh that is affixed to the hydrowire using a custom crossbow system. There is a bookend clamp that is used to affix the cod end to the net so that it maintains a vertical structure during ascent and descent, and a 25 kg weight is added to the bottom of the system (total system weight in air is ~50 kg). The net is vertically towed from the surface to near-bottom or 1000 m, whichever is shallower. Therefore, at least ~1200 m of wire is required. An image or video of the system can be provided upon request. For Leg 2 (NL AZMP) uses a dual-202 micron net system that does not utilize a crossbow system. This setup uses a custom dual frame with single pickup point in the middle of both nets, and a weight is attached to the bottom of the frame to keep the nets in a vertical orientation. For Leg 3, an Hydrobios Multinet Sampler of 0.25m2 with 200 micron mesh net will be deployed. The instrument weighes ~150 kg and and is 7 m in height. The instrument is deployed vertically down to 1000 m ideally using an EM cable. During a previous mission on the Atlantis this instrument was lowered over the side of the vessel using the aft-crane and was then connected to the CTD/Rosette cable for its operation in the water. | |||||||||||

Over the Side Equipment
NL AZMP leg 2 requires a buoy to be deployed using the aft-mounted A-frame.
Drifters will be deployed over the side of the vessel, starboard or port, and can freefall into the water from deck height, similarly to the Argo floats.

Additional Information
We will conduct 24 hour operations, with 2 x 12 hour shifts from 6 - 6 (MAR AZMP Leg 1 and AZOMP Leg 3) and 12 - 12 (NL AZMP Leg 2). This could be adjusted to accommodate meal times or other ship operations. Primary operations for the majority of the mission will consist of CTD/Rosette deployment, vertical ring net tows, and Multinet tows.
The deployment of 17 Argo floats will occur during the mission. These are normally done off the stern of the vessel, and may require assistance from the ship's tech on duty. A rope is normally used to gently lower the float over the side of the vessel, where it is then let go once it touches the surface.
- Use of the ship's 300 KHz ADCP is also requested.
- While in the Gully Marine Protected Area, the vessel is requested to maintain distance gaps and speeds less than 10 knots, in compliance with Fisheries and Oceans Canada's Marine Mammal Regulations: https://laws-lois.justice.gc.ca/PDF/SOR-93-56.pdf (see section 38)
- A IFCB flowcam will be provided by a WHOI scientist. This will have to be plumbed into the existing underway system.
- Additional science container(s) may be loaded in Halifax, NS, depending on the location and placement of the UNOLS RadVan.
