From 2004 to 2014, the Line W moorings measured a 0.7 Sv yr−1 slowing of deep western boundary current (DWBC) offshore Cape Cod. Here, we combine these mooring observations with float and satellite altimeter data find that this DWBC change corresponded cross-basin Atlantic Meridional Overturning Circulation (AMOC) about 0.3 yr−1. Our AMOC transport time series corresponds well Estimating Climat...

A bottom mounted upward looking Simrad EK60 120-kHz echo sounder was used to study scattering layers (SLs) and individuals of the krill Meganyctiphanes norvegica. The mooring was situated at 150-m depth in the Oslofjord, connected with an onshore cable for power and transmission of digitized data. Records spanned 5 months from late autumn to spring. A current meter and CTD was associated with t...

In my opinion, the main handicap of this study is an inadequate dataset used for the stated objectives. The authors are trying to describe a seasonal signal, as well as discern a seasonal signal from short-term intra-seasonal decay events, using data from a single year. The (roughly) bi-monthly sampling regime is inadequate to capture meaningful data on the sub-seasonal events. The records capt...

This presentation describes work undertaken as part of INNOVATE UK funding led by Witt Energy Ltd to investigate the efficacy of a novel design of wave energy converter (WEC). A sealed spherical hull is floating on the surface of the water (Fig. 2(b)) and is moored to the sea bed under a four point catenary mooring system. A mechanical device known as the WITT (Fig. 1) is housed within the hull...

The mean structure and variability of the North Equatorial Current/Undercurrent (NEC/NEUC) are investigated with one-year Acoustic Doppler Current Profilers measurements from 4 subsurface moorings deployed at 10.5°N, 13°N, 15.5°N, and 18°N along 130°E in the western Pacific. The strong westward flowing NEC ranges from the sea surface down to 400 m, and the mean zonal velocity of the NEC at 10.5...

[1] Numerous eddies have been identified in a seven year time series of mooring observations in the Canada Basin, Arctic Ocean. We focus on a series of deep eddies centered at 1200 m depth, and occupying up to 1500 m of the water column. The deep eddies are found to be spatially localized, only ever being observed at one of four mooring sites of the Beaufort Gyre Observing System in the Canada ...

Each REU student will work with (at least) one faculty advisor and (at least) one IGERT PhD mentor. Here we present twelve example research projects in some detail, overview in Table 1. The specific research projects will depend on the background and interest of the REU applicants and the evolving research among the IGERT faculty and graduate students.

The turbulence regime near the crest of a biologically rich seamount of the Mid-Atlantic Ridge southwest of the Azores was registered in high spatial and temporal resolution. Internal tides and their higher harmonics dominate the internal wave motions, producing considerable shear-induced turbulent mixing in layers of 10-50 m thickness. This interior mixing of about 100 times open-ocean interio...

Many innovative floating offshore structures have been proposed for cost effectiveness of oil and gas exploration and production in water depths exceeding one thousand meters in recent years. One such type of platform is the offshore floating Spar platform. The Spar platform is modelled as a rigid body with six degrees-of-freedom, connected to the sea floor by multicomponent catenary mooring li...
