Operations Area: offshore North Carolina

Lat/Lon: 35° 0.0′ N / 75° 0.0′ W

Depth Range: 200 / 3000

Will the vessel be operating within 200 NM of a foreign country? no

Science objectives

Recover 2 bottom pods along 250 m isobath and PIES in approx 2800 m using a large ROV

Science Activities

limited - run ADCPs in support of ROV operations, possibly XBTs

R/V Armstrong

Shipboard Equipment

Bathymetry System 12 kHz
ADCP 300 kHz
Sippican XBT System (Mark 21)
ADCP 150 kHz
A-Frame
Science Underway Seawater System
Dynamic Positioning System
USBL Nav
ADCP 38 kHz
Crane
EM710 MkII (40 to 100 kHz) Multibeam Echosounder


Shipboard Equipment Notes: We will focus on recovery of the bottom pods and PIES using an Oceaneering Comanche ROV.  Monitoring current speeds with the ADCPs will be critical.  We will also need sound speed, determined with either/both XBTs and CTDs. Near bottom navigation will be supported by USBL system.

Shipboard Communication

Basic Internet access via HiSeasNet
Is there a need to receive data from shore on a regular basis?


Shipboard Communication Notes: We will be accessing simple imagery (SST and surface current maps) to assess Gulf Stream position during operations.  Files will not be large (< 1MB).

CTD/Water Sampling

911+ Rosette 24-position, 10-liter bottle Rosette with dual T/C sensors

Critical CTD Sensors: 

Storage Notes:

Navigation

GPS
USBL

Navigation Notes: The ROV needs to integrate surface navigation and USBL information for near-bottom navigation.  There has been separate communications about specific models of equipment available.


Winch Notes: I'm uncertain about winches at this time.  Oceaneering has said they will not be able to use the ship's fiber optic as an umbilical so presumably they are bringing their own.  I don't know if they will bring their own winch.



Wire Notes:

Slip ring required? no	Number of conductors:
Non-standard wire required? no	Type:

Over the Side Equipment

Will you be bringing any equipment (winches, blocks, etc.) that lowers instruments over the side? yes

Details: Oceaneering will bring significant equipment to support the ROV, including vans to be attached to the deck, possibly a winch.
