Pinnipeds as ocean-temperature samplers: calibrations, validations, and data quality

Pipeline Calibrations of ACS Data

Our strategies for collecting ACS calibration data, and converting it into reference files for use in the calibration pipeline, have been continually evolving since the instrument was installed during Hubble Servicing Mission 3B in March of 2002. We provide an historical overview of basic ACS pipeline calibrations, including the impact that some of the more recent changes have on downstream dat...

Synthetic Population Generation: A Heuristic Data-Fitting Approach and Validations

Fronts in the Southern Indian Ocean as inferred from satellite sea surface temperature data

Sea surface temperature (SST) derived from the weekly measurements made by the Advanced Very High Resolution Radiometers (AVHRR) of NOAA satellites was used to investigate the structure and space-time variability of large-scale fronts in the Southern Indian Ocean (30–60jS and 20–150jE) during the period of 1997–1999. Monthly SST gradient maps provided an overall view of five basic fronts: the N...

SCUBA divers as oceanographic samplers: The potential of dive computers to augment aquatic temperature monitoring

Monitoring temperature of aquatic waters is of great importance, with modelled, satellite and in-situ data providing invaluable insights into long-term environmental change. However, there is often a lack of depth-resolved temperature measurements. Recreational dive computers routinely record temperature and depth, so could provide an alternate and highly novel source of oceanographic informati...

Improved oxygen isotope temperature calibrations for cosmopolitan benthic foraminifera

Despite decades of use as a paleoceanographic proxy, considerable uncertainty still surrounds the temperature dependence of benthic foraminiferal dO. Widely applied paleotemperature equations may mix non-equilibrium foraminifera with equilibrium synthetic calcite, resulting in temperature sensitivities that are too large. Warm-water foraminiferal calibrations may give temperature sensitivities ...
