The RV Ronald H. Brown traveled a section of tropical Atlantic waters northeast of Barbados during January-February 2020 in an international collaboration effort known as Elucidating the Role of Clouds Circulation Coupling in Climate Campaign (EUREC4A). ATOMIC (Atlantic Trade-wind Ocean–Atmosphere Mesoscale Interaction Campaign) was the US contribution to EUREC4A focused...
High-resolution ship-based observations of a nearly uniform stratocumulus deck in the southeast Pacific during 17 days of the 2008 VOCALS regional experiment elucidate radiation and turbulence in the marine boundary layer (MBL). A new method for prescribing observations-based cloud properties to the Rapid Radiative Transfer Model is presented and applied...
In this thesis, data collected during the Dynamics of the Madden Julian Oscillation (DYNAMO) field campaign, conducted in the Indian Ocean in Fall of 2011, is used to compute heat fluxes at the air-sea interface by evaluating eddy covariances and bulk aerodynamic formulae. Errors in daily average gridded fluxes computed...
Uncertainties in general circulation model (GCM) representations of marine boundary layer (MBL) shallow cloud cover contribute substantially to the spread in model predictions of future climate. Further uncertainties in GCM output arise from an incomplete understanding of cloud-aerosol interactions. For example, the Fifth Assessment Report from the Intergovernmental Panel on...

Sea surface temperature (SST) was measured by several instruments deployed from the research vessel Sally Ride in the Bay of Bengal for the Monsoon Intraseasonal Oscillations in the Bay of Bengal (MISO-BOB) 2019 field experiment. This data set presents 1 minute averages of 3 m SST from the Scripps Institution...
This report details ocean water salinity and stable isotope measurements (deuterium (D) and 18O) in water collected from April 17 2018 to April 21 2018 in the coastal waters of Oregon, USA. Measurements were made from surface, ship flow-through, and CTD rosette bottle samples collected as part of a student-led...
In winter and spring, ice-coast interactions driven by winds and ocean currents cause sea ice fractures (leads) to form repeatedly along Arctic coastlines. These events are often associated with rapid and expansive changes in sea ice drift and state that are challenging to predict and represent in models. We investigate...
from the summer dry season to the winter wet season. Such movement that connects summer and winter habitats may be particularly important for coho salmon, O. kisutch, because availability of overwintering habitat can limit freshwater survival for this species. Here, I describe basin-scale variability in the spatial pattern of fall...
We consider long planetary waves of annual period linearized about a steady, wind-driven subtropical (ST) gyre circulation. The circulation divides the gyre into an eastern zone (EZ) where only the surface layer is in steady motion and a western zone (WZ) where both the surface and the middle layer are...
In many scientific settings, investigators are interested in the effect of a new treatment. To have a point of comparison data is collected from patients before treatment groups are assigned. When seeking to test the presence of a significant treatment effect it may be unclear how baseline measurements should be...
