Modern dirty sea ice characteristics and sources: The role of anchor ice
Received 23 September 2010; revised 18 May 2011; accepted 14 June 2011; published 13 September 2011. [1] Extensive dirty ice patches with up to 7 kg m sediment concentrations in layers of up to 10 cm thickness were encountered in 2005 and 2007 in numerous areas across the central Arctic. The Fe grain fingerprint determination of sources for these sampled dirty ice floes indicated both Russian a...
متن کاملAnchor ice and benthic disturbance in shallow Antarctic waters: interspecific variation in initiation and propagation of ice crystals.
Sea ice typically forms at the ocean's surface, but given a source of supercooled water, an unusual form of ice--anchor ice--can grow on objects in the water column or at the seafloor. For several decades, ecologists have considered anchor ice to be an important agent of disturbance in the shallow-water benthic communities of McMurdo Sound, Antarctica, and potentially elsewhere in polar seas. D...

Aggregations of ice platelets accumulate below the annual sea ice (subice platelet layer) and on the bottom (anchor ice) to depths of 33 meters. Observations of ice platelets adhering to submerged lines support the conclusion that 33 meters is the lower limit for ice formation in the water column in this area. The rising anchor ice lifts epibenthic fauna and has a pronounced effect on the distr...
متن کاملAnchor Modeling
Did you know that some of the earliest prerequisites for data warehousing were set over 2500 years ago. It is called an anchor model since the anchors tie down a number of attributes (see picture above). All EER-diagrams have been made with Graphviz. All cats are drawn by the author, Lars Rönnbäck. 2 2 You can never step into the same river twice. 2 The great greek philosopher Heraclitus said "...

Flow tracking is an integral aspect of many network-related applications, including intrusion detection, network administration, per-flow billing, and network engineering. While some applications do not require precise tracking of every packet or flow and successfully employ statistical sampling or approximations to achieve an acceptable level of accuracy, many others, especially in the securit...
