Summary: | Authors: Sienna N. Blanckensee Data sources: Detailed data sources are referenced in the associated paper and supplementary materials. Summary: The discovery of Antarctic Bottom Water formation in Cape Darnley, East Antarctica, in 2013 represents a significant advancement. This data product presents the first comprehensive ocean climatology of the Cape Darnley and western Prydz Bay region, compiled from various hydrographic sources including CTD, Argo, and Seal CTD. Consisting of three netCDF files, it includes raw compiled data points, mean values at different depth intervals, and gridded data at corresponding depths. This dataset aims to prevent repetitive and streamline data collation, conversion, and quality control efforts by providing a multi-source collated dataset up to 2023. Utilised in the referenced paper, this dataset facilitated the quantification of two dense shelf water sources from Cape Darnley, assessment of preconditioning from Prydz Bay, and characterisation of the water masses in the region. Additionally, an accompanying Jupyter Notebook ("data_prodct_cape_darnley_ocean_slices.ipynb") illustrates data access and basic plotting procedures, while supplementary Jupyter Notebooks detail figure creation methods in the referenced paper. Keywords: Cape Darnley, East Antarctica, Antarctic Bottom Water, Dense Shelf Water, data product, CTD, autonomous floats, ships, elephant seals Methodology: Detailed methodologies for data collation, processing, and analysis are outlined in the associated paper. Mean values were computed at standardized depth intervals (every 50m in the top 1000m and every 100m for depths greater than 1000m), with separate gridded datasets (0.1° by 0.1° grid cells) generated to mitigate biases from co-located data points. Refer to "data_prodct_cape_darnley_ocean_slices.ipynb" for code implementation details. Data description: Extent: 63-73°E & 63-68.5°S Variables: temperature, conservative temperature, salinity, absolute salinity, oxygen, latitude, longitude, pressure, depth, ...
