The AW current also carries Atlantic plankton into the Arctic Basin and this inflow of zooplankton biomass through the Atlantic-Arctic gateway far exceeds the inflow through the shallow Pacific-Arctic gateway. However, because this transport has not yet been adequately quantified based on observational data, the present contribution is poorly defined, and future changes in Arctic zooplankton communities are difficult to project and observe. Our objective was to quantify the inflow of zooplankton biomass through the Fram Strait during different seasons, including winter. We collected data with high spatial resolution covering hydrography (CTD),currents (ADCP and LADCP) and zooplankton distributions (LOPC and MultiNet) from surface to 1,000 m depth along two transects crossing the AW inflow during three cruises in January, May and August 2014. Long-term variations (1997–2016) in the AW inflow were analyzed based on moored current meters. Water transport across the inflow region was of the same order of magnitude during all months (January 2.2 Sv, May 1.9 Sv, August 1.7 Sv). We found a higher variability in zooplankton transport between the months (January 51 kg C s −1 , May 34 kg C s −1 , August 50 kg C s −1), related to seasonal changes in the vertical distribution of zooplankton. However, high abundances of carbon-rich copepods were observed in the AW inflow during all months. Surface patches with high abundances of C. finmarchicus, Microcalanus spp., Pseudocalanus spp., and Oithona similis clearly contributed to the advected biomass, also in winter. The data reveal that the phenology of species is important for the amount of advected biomass, and that the advective input of zooplankton carbon into the Arctic Basin is important during all seasons. The advective zooplankton input might be especially important for mesopelagic planktivorous predators that were recently observed in the region, particularly during winter. The inflow of C. finmarchicus with AW was estimated to be in the order of 500,000 metric tons C y −1 , which compares well to modeled estimates

    EU Competition Law in the Digital Era: What to Tell About Intel?

    No full text
    Intel, a US-based company, was fined by the European Commission in 2009 for abusing its dominant position at the computer processor market intended to exclude its competitor AMD from that market. The penalty amounting to €1.06bn was the largest antitrust fine in the Commission’s history at the time. As the EU General Court had rejected Intel’s appeal in 2014, the matter was brought before to EU Court of Justice. The CJEU judgment, rendered in September 2017, is controversial for at least two reasons. First is the territorial reach of the EU competition law outside the EU borders, and second relates to the treatment of exclusivity rebates. With regards to the former, for the first time the CJEU confirmed the position of the Commission and the General Court regarding the extended territorial reach of the EU anti-trust legislation. Quite the opposite, the CJEU quashed the General Court ruling as to the former, arguably rejecting the traditional per se infringement of exclusivity rebates and embracing the effects-based analysis. The doctrine is somewhat divided as to whether this judgment is a much needed clarification of the two issues or it indicates a new direction in EU competition law analysis. This paper is addressing the most important ideas in the doctrinal interpretations and related arguments, and provides critical assessment of the present state of affairs. It also raises certain points relevant to the Intel judgment, which so far have not been given sufficient attention in the case comments and scholarship
