Into the North Atlantic. First

A Heinrich event is a natural phenomenon in which large groups of icebergs break off from the Laurentide ice sheet and traverse the Hudson Strait into the North Atlantic. First described by the marine geologist Hartmut Heinrich, they occurred during five of the last seven glacial periods over the past 640,000 years. Heinrich events are particularly well documented for the Wisconsin glaciation, during the Last Glacial Period, but notably absent from the Penultimate Glacial Period. The icebergs contained rock mass that had been eroded by the glaciers, and as they melted, the material was dropped to the sea floor as ice rafted debris and formed deposits called Heinrich layers.

Flanker is a position in the sport of rugby union. Each team of 15 players includes two flankers, who play in the forwards, and are generally classified as either blindside or openside flankers, numbers 6 and 7 respectively. The name comes from their position in a scrum in which they 'flank' each set of forwards. They compete for the ball – most commonly in rucks and mauls. Flankers also assist in pushing in a scrum, but are expected to detach from the scrum as soon as the ball is out to get to the play before the opposition's forwards. Flankers also participate in line-outs, either being lifted to contest or win possession, or to lift other players. Flankers are usually the key participants in the tackling process. The flankers, especially the openside, are often the fastest forwards on the team but still relied upon for tackling.
