The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv
attribute NC_GLOBAL acquisition_description String All experiments were performed\u00a0using the MIT General Circulation Model
(MITgcm) [Marshall et al., 1997a, b]. The model was configured to allow non-
hydrostatic dynamics to explicitly resolve deep convection, and the set-up was
modified from Jones and Marshall [1993]. The model domain was a box with
periodic boundary conditions in the x\u00a0and y\u00a0directions of 32 x 32 km
with a horizontal\u00a0resolution of 250 m. The box had a uniform depth of 2
km with 41 z-levels with increasing thickness\u00a0from 10 m
at\u00a0surface\u00a0to 100 m near the bottom. The linear equation of state
was\u00a0used throughout this study. 16 sensitivity experiments were designed
to explore the behavior of oxygen uptake during the deep convection events
under different cooling conditions. Two validation runs were also applied by
forcing the model using observational data from Argo
[(http://www.argo.net/](\\"http://www.argo.net/\\")). Detailed information
about all simulations can be found in Sun et al [2017]. In this data set,
horizontally averaged profiles and vertical transport of dissolved oxygen and
temperature from all experiments are included. A few transect of dissolved
oxygen and temperature are also included to demonstrate the evolution of the
convection event.\u00a0

attribute NC_GLOBAL projects_0_description String NSF abstract:
Recent observations and climate model projections indicate that the global oxygen inventory may be declining due to the lower solubility and the increasing stratification associated with a warming climate. Decomposition of organic matter in the deep sea consumes dissolved oxygen, which must be replenished by the circulation of oxygen-rich waters from the polar regions. Without vigorous oxygen supply from the high latitudes, the global oceans will lose oxygen.
In this study, researchers at Georgia Tech will use a hierarchy of models to simulate oxygen and nutrient cycling in the Labrador Sea, one of the regions of deep water formation in the North Atlantic, over a fifty year period. The Labrador Sea is also a region of extreme seasonality and intense biological productivity, thus oxygen cycling there likely reflects multiple physical and biological processes. Results from this study will promote a better understanding of the interannual variability of oxygen and nutrients in the Labrador Sea, and ultimately contribute to knowledge on how a changing climate impacts these cycles.
Broader Impacts:
The broader impacts of this project include student training, international collaboration and outreach to K-12 students.
