Science Objectives

This project investigates the sources of water feeding the Denmark Strait Overflow
Water. It is a collaborative field program between the Woods Hole Oceanographic
Institution (WHOI), the Marine Research Institute of Reykjavik (MRI), the University of
Bergen (UIB), and the Netherlands Institute for Sea Research (NIOZ). Our approach is to
deploy a year-long set of moorings from August 2011 to August 2012, and carry out a
shipboard hydrographic/velocity survey of the region during the mooring deployment and
recovery cruises. Moorings will be maintained upstream of the Denmark Strait sill in the
major components of the circulation, as well as in the overflow water at the sill itself (see
the attached figure showing the mooring locations). The main scientific objective of the
program is to quantify the different water mass components, transports, and pathways
feeding the overflow water, and to understand the dynamics of the warm-to-cold
conversion of water that forms the overflow.

Science Activities

The primary activities on the 2011 cruise are as follows:
(i) Mooring Work (see the attached figure showing the mooring locations). We will
deploy 12 new moorings across the northern part of Denmark Strait along the Kogur Line
(Note: a PIES instrument will also be deployed along the line for IFM-Hamburg).
Additionally, we will turn-around 4 existing moorings, 1 near the Denmark Strait sill and
3 to the northeast at the Hornbanki Line.
(ii) CTD Survey (see the attached figure showing tentative CTD lines). We will carry-out
a CTD survey, on the order of 300 full-depth casts. Water sampling will be minimal (salt
samples only).
(iii) Velocity survey. We will use the vessel-mounted ADCPs extensively to survey the
water currents.

Additional Info

Pre-cruise Planning Meeting: Visit WHOI
Media personnel on board: Video, Writer, Teacher(s)
We have two types of outreach. (1) A team of 4-5 people will be performing outreach for the general public and for school children in roughly 10 schools. We will have onboard 1-2 teachers, a writer, a photographer, and a videographer. (2) We will have a camera man from National Geographic TV onboard, filming for an episode in an upcoming show about the oceans.

Notes: Note: After the mooring work is completed (approximately 10 days into the cruise) we
will drop off 7 members of the science party (including the mooring technicians) at a
coastal town in northern Iceland. This will likely be Siglufjordur (see the attached map of
Iceland). This requires use of the small boat (this has already been discussed with the
port office and the master).
