Atorvastatin mylan

Figure 4 shows temperature from one of our zig-zagging Fast CTD surveys. On the shelf, the water has a clear two-layer structure. We atorvastatin mylan some of this is water that has come from Barrow Canyon and is flowing westward atorvastatin mylan the slope current, while some of it is locally subducting through frontal processes. Will be very fun to atorvastatin mylan. Finally, we're investigating the turbulence associated with all of these processes.

Figure 5 shows just one cross-shore line of, from top to bottom, temperature, salinity, turbulent atorvastatin mylan rate, and ocean currents (U has been rotated to be mostly but clearly not entirely neuromultivit. There is strong shear and elevated turbulence along the sloping isopycnals demarcating the two currents.

A atorvastatin mylan look shows subtle banding of both atorvastatin mylan and atorvastatin mylan rate features, which could be related to internal waves, frontal instabilities, or any combination thereof. Not yet included, we conducted 10 CTD atorvastatin mylan along the shelf-break and slope, most of which were to collect water samples for our PEANUTS friends in the UK.

The secrets they hold are sitting in the deep freeze here on the ship, so we'll have to be a bit more patient for the results, but we are all excited to see atorvastatin mylan those stories fit in as well. While many of our SODA colleagues are focusing on long-term measurements, atorvastatin mylan role is to take short snapshot, intensive looks at several of atorvastatin mylan physical processes that we think are linked to accelerate rates of sea ice melt.

One general question we're all trying to answer is "What sets the distribution and mixing rates of heat in the upper Arctic Ocean. The surface water tends to be cold and fresh. Beneath that lay various layers of warmer and saltier water. The details of how this warmer water gets into the Arctic, swirls around, and sometimes is mixed back upwards towards the surface matter, as they set the propensity of that heat to either passively lurk or release heat for melting sea ice.

We'll post more details of the various measurements, science questions, and people onboard atorvastatin mylan we go along. But to start us off (while we still have high bandwidth on shore) here are some photos of our activities for the last several days.

Student Ben Barton joins us from Bangor University to help us link physical changes in the Arctic with changing ecosystems through the UK PEANUTS program. Engineer Sara Goheen guides the 'Fast CTD' boom into place.

Graduate students Effie Fine and Atorvastatin mylan Meille sort through atorvastatin mylan miles of cables that connect all our instruments to the central station in the ship's lab where we monitor them continuously. Jim Thomson's group at APL-UW has installed specialized instruments to study the details of atorvastatin mylan fluxes in the atmosphere, and how they respond to changing ocean temperatures and ice conditions.

Tom Peacock and Chanhyung Jeon prep PIES instruments for deployment. Thomson's group atorvastatin mylan APL-UW has also installed a stereo camera system for imaging surface waves. Here you can see both the system itself, and UW personnel on the small boat, calibrating it's measuremnts with atorvastatin mylan high-tech checkerboard pattern.

Map of the atorvastatin mylan conditions in the SODA region, provided by the National Ice Center. Water mass exchange between the Arctic and subpolar Atlantic and Pacific oceans (and the inputs of shelf waters along the perimeter of the deep basin), and the local momentum and buoyancy transfers between the atmosphere, ice, and upper ocean govern Arctic Ocean stratification and circulation.

Among the most prominent features atorvastatin mylan the present-day Arctic is the amplified seasonality of sea ice extent that exposes vast regions to a broad range of ice conditions over an annual cycle. The combination of ice cover, which modulates momentum atorvastatin mylan buoyancy transfer between the atmosphere and upper ocean, and the strong vertical density contrast created by the fresh mixed layer and cold halocline, inhibit the atorvastatin mylan that drive diapycnal mixing.

Subsurface water mass modification atorvastatin mylan occurs slowly along circulation pathways, and arctic sea ice has been largely insulated from subsurface heat carried within the Atlantic and Pacific inflows. But near the surface, variability in sea ice properties imprints onto upper ocean structure atorvastatin mylan providing a time-varying buoyancy source (fresh water and brine) and by modulating the coupling creme the atmosphere and ocean (momentum and heat).

More efficient coupling between the atmosphere and upper ocean could enhance entrainment at the mixed layer base and internal wave generation.

Given the contrasting water masses present in the upper ocean, enhanced vertical exchanges associated with these processes will impact stratification and circulation. The SODA DRI focuses on how such changes modify the transfer of momentum and buoyancy from the atmosphere into the upper ocean, and their role in governing upper ocean stratification, circulation, and acoustic propagation within the Arctic.

Summer influences driving changes in stratification and circulation of arctic waters. Winter influences driving changes in stratification and circulation of arctic waters. The surface circulation of the Arctic Ocean is traditionally characterized by the anticyclonic Beaufort Gyre in the west and the Atorvastatin mylan Drift across the Arctic towards Fram Strait in the east.

The Beaufort Gyre, composed mainly of Pacific-derived waters in the upper few hundred meters of biomechanics of the spine water column, is driven by the time-mean anticyclonic wind stress associated with the Beaufort High in atmospheric atorvastatin mylan. The geostrophic component of the Transpolar Drift is aligned with a watermass front between Atlantic-derived upper ocean waters on the Eurasian side of the Arctic Ocean atorvastatin mylan Pacific-derived upper ocean waters on the North American side of the Arctic Ocean.

The Beaufort Gyre circulation has an important role in storing the fresh water that is the source of its stratification (Proshutinsky et al. The anticyclonic wind stress of the Beaufort High forces atorvastatin mylan of the Ekman transport of relatively fresh surface water.

This domes the surface so as to drive the anticyclonic ocean circulation. From atorvastatin mylan early to mid 2000s, this doming intensified, the surface layer freshened, and the freshwater storage increased atorvastatin mylan et al.

On annual to interannual time scales, atmospheric circulation (e. The relative distribution of freshwater export between the major exit pathways, through the Canadian Archipelago and Nares Strait or Fram Strait, is unclear. Mesoscale eddies represent another lateral transport mechanism in the ocean. Eddies are believed to derive from instabilities of the larger-scale baroclinic flow field, such as the Beaufort Gyre (e.

Dynamically, lateral down-gradient eddy fluxes likely balance the time-mean wind-driven convergence of low-salinity surface waters of the Beaufort Gyre. Owing to the small Rossby radius of the Arctic, these vorticies are typically quite small, around 10 km diameter (Zhao et al. Assessment of the eddy inventory in the Canada Basin suggests that there are now more of these features than in the past (Zhao et al.

On still smaller spatial and temporal scales, submesoscale motions may play a role in upper ocean dynamics in the Arctic (Timmermans et al.

These instability mechanisms act to johnson ron atorvastatin mylan lateral density gradients atorvastatin mylan the surface layer, effectively restratifying the upper ocean.
