  1. Scavenging and transport of thorium radioisotopes in the North Atlantic Ocean

    Lerner, PaulMassachusetts Institute of Technology and Woods Hole Oceanographic Institution2018

    Many chemical constituents are removed from the ocean by attachment to settling particles, a process referred to as “scavenging.” Radioisotopes of thorium, a highly particle-reactive element, have been used extensively to study scavenging in the ocean. However, this process is complicated by the …

  7. Key mechanisms of surface water pCO2 variability in the North Atlantic Ocean

    Krijnen, JustinUniversity of East Anglia2013

    A proxy for the North Atlantic gyre circulation has been developed, using sea-surface height from altimetry. In conjunction with the winter North Atlantic Oscillation (NAO) index, statistical analysis has been applied to understand the key mechanisms of surface water partial pressure of CO2 (pCO2) …

    During Cold Air Outbreak (CAO) events over North America during winter, cold dry air is often advected over the ocean offshore of the East Coast. A motivating hypothesis of this study is that the air-sea fluxes associated with CAO events will be manifested in offshore ocean variations that will be …
