Atlantic Water Inflow Through the Yermak Pass Branch: Evolution Since 2007

چکیده
Thirty-four months (2017–2020) of mooring data were recently obtained at 80.6°N, 7.26°E in the main branch Atlantic Water inflow to Arctic, Yermak Pass Branch. The Branch was sampled that same location during 14 a decade ago (2007–2008) when sea ice abundant (mean sea-ice concentration 74% vs. 39% recent deployment). We focus on time scales larger than 50 hr. new set shows an increase velocity variations 40% compared 2007–2008 period. Year 2018 exceptional with ice-free conditions over entire year and intensified mesoscale activity other years.

متن کاملCLUSTER EVOLUTION SINCE z ∼ 1
We have used the Advanced Camera for Surveys (ACS) on the HST to obtain optical imaging of a sample of 8 galaxy clusters in the redshift range 0.8 < z < 1.3. The ACS data provides accurate photometry and the ACS high angular resolution makes it possible to obtain crucial morphological information of the cluster galaxy populations. These data are supported by X-ray observations and by ground bas...

Trade promotions are the most important promotional tool available to a manufacturer. However trade promotions can achieve their objective of increasing short-term sales only if the retailer passes through these promotions. Empirical research has documented that there is a wide variation in retail pass-through across products. However little is known about the variations in pass-through over ti...
متن کاملVolatility and Pass-Through
What drives countercyclical volatility? A large literature has documented that many economic variables are more disperse in recessions, but this could either occur because shocks get bigger or because rms respond more to shocks which are the same size. Existing evidence that the dispersion of endogenous variables rises in recessions cannot tell us which of volatility or responsiveness is getti...
