    The calving of the Mertz Glacier occurred in 2010 in East Antarctica, brought on by the re-positioning of a large iceberg. Using satellite data, this study shows a reduction in sea ice production following the calving, interpreted as a potential regime shift towards reduced sea ice production for the coming decades.

    Ocean circulation moves heat and gases between the ocean and atmosphere, impacting the carbon cycle at decadal timescales. Here, a radiocarbon coral record of ocean mixing from Bermuda suggests that the formation of mode water, and thus carbon uptake, have been more stable over the past 200 years than previously thought.

    Many organisms are responding to a warming climate by shifts in spatial distribution. The poleward movement of silver hake,Merluccius bilinearis, over the last forty years is related to the position of the Gulf Stream and Atlantic meridional overturning circulation through changes in local bottom water temperature.

    Storm water runoff and wastewater effluent are discharged into oceans, but the full ecological effects of these discharges are unknown. Here, the authors examine the population structure of a marine organism, the bat star, and show that these discharges alter the genetic structure and larval dispersal of this species.

    Ocean acidification due to increasing carbon dioxide levels can affect the growth and viability of corals. In this study, the authors measured extension, calcification and density in Florida corals collected in 1996, and show that recent climate change did not cause a decline in their extension or calcification.

    The origin of the Atlantic Multidecadal Oscillation, a semi-periodic variability of sea-surface temperature, is unknown. Knudsenet al.show that 55- to 70-year climate oscillations existed throughout the last 8,000 years, suggesting that the Atlantic Multidecadal Oscillation is a permanent feature of the Holocene climate induced by internal ocean variability.

    Antarctic bottom water is important for the global climate system, but its main source in East Antarctica was altered recently because of calving of the Mertz Glacier Tongue. The authors model this event and find large changes in dense water exports from the region.

    Ocean tides and infragravity waves—the Earths 'hum'—have very different periods and wavelengths. Sugioka and colleagues report resonance between these two phenomena using arrays of broadband ocean-bottom seismometers and show that some tidal energy is transferred to the deep oceans through this coupling.
