Fig. 3: CTD and seafloor pressure–temperature data spanning the small cooling event of April 2014.

This event was clearly registered at both Holes U1382A and U1383C (Fig. 2). a Plots of Conservative Temperature, Absolute Salinity, neutral density, and oxygen saturation of bottom waters over North Pond for two CTD casts in 2014 that bracketed the cooling event. Properties from the 29 March CTD cast are shown in red, properties from the 14 April CTD cast in blue. The dark centers of the Absolute Salinity profiles show results of smoothing using a ∼0.5 m box filter. b Expanded record of seafloor pressures recorded at Hole U1382A (cyan) and bottom water in-situ temperatures recorded at Holes U1382A (red) and U1383C (blue) during the first six months of 2014, illustrating the fortnightly (∼biweekly) cycles in tidal amplitudes in North Pond and the times of the two 2014 CTD casts relative to these cycles.
