TL;DR: In this article, the authors argue that this cooling event was forced by a massive outflow of fresh water from the Hudson Strait, based on the estimates of the marine 14C reservoir for Hudson Bay which, in combination with other regional data, indicate that the glacial lakes Agassiz and Ojibway (originally dammed by a remnant of the Laurentide ice sheet) drained catastrophically ∼8,470 calendar years ago; this would have released >1014 m3 of freshwater into the Labrador Sea.

TL;DR: T tidal peatlands are unlikely to indefinitely survive a higher rate of sea‐level rise in the absence of a significant source of mineral sediment, and could deviate from this value depending on variation in plant productivity, root:shoot ratio, suspended sediment concentration, sediment‐capture efficiency, and episodic events.

TL;DR: In this article, the isotopic characteristics of siliciclastic sediments delivered by the Laurentide, Greenland, Iceland and Fennoscandian ice sheets to the North Atlantic were determined for twenty-six samples of Late Quaternary, fine-grained ( −15) IRD comprising H3 and H6.

TL;DR: In this article, a series of nine piston cores from the axis of Baffin Bay and across the Davis Strait sill were used to provide a suite of 21 AMS 14 C dates on foramininfera which bracket the ages of several detrital carbonate-rich (DC-) layers.

TL;DR: It is believed that thenew collapse mechanism disagrees with important data and that MacAyeal’s original model remains viable after appropriate modifications, but that a new ice-shelf-collapse mechanism may work.
