Alkenone core top data (UK'37, UK'38ME, UK'38ET, UE'36OME, K38ME/K37, K37/K38) from 168 samples that span a geographic region from from 76.75°N -76.5°S and 178.8E-179.6W. Data were collected for calibration of alkenone indices to sea surface temperature. Also included are alkenone data (UK'37, UK'38ME, and SST estimates) from 12 early Pliocene age samples from ODP sites 1143 and 806, which were collected to constrain the behavior of UK'38ME relative to UK'37 at warmer than modern ocean SSTs. Data were collected via gas chromatography-flame ionization detection Agilent 214 7890N Series instrument with splitless injection and Restek Rtx-200 ms (105 m x 250 µm x 0.25 x 215 µm) poly(triflouropropylmethylsiloxane) stationary phase semi-polar column.
