The Davis Aerodrome Project (DAP) collected a range of environmental survey data over several field seasons to support a comprehensive environmental assessment of the proposed aerodrome. This data includes flora, fauna, soils, lake ecosystem, nearshore, marine, air quality and meteorological information which has been collected by a number of different methods, and extends across the current Davis Station, proposed aerodrome and supporting infrastructure footprint (Ridge Site), previous sites considered for the aerodrome (Heidemann Valley, Adams Flat), as well as locations across the Vestfold Hills away from any of the proposed developments.(this text is standard for all DAP datasets being added to the AADC). This dataset contains short-term nearshore marine current profile data collected to inform environmental assessment processes related to the Australian Antarctic Division’s DAP and Davis Masterplan projects. Eight current meter deployments were undertaken across six sites in the nearshore marine environment in the vicinity of Davis Research station. Deployment periods ranged from three days (3 x 24hr tide cycle) to two weeks. Sites were selected based on the location of previous sampling activity (CM1-5) and sites of interest to Davis Aerodrome and Davis Masterplan projects with regard to proposed future developments in the area. A second deployment was undertaken at two key sites to increase the sampling interval at each. Data was collected using a Nortec Aquadopp Profiler 1 MHz. The same instrument was used to collect current profiles at all sites. The instrument was deployed through a 40cm hole drilled through the seaice. It was suspended horizontally in the water column (mid-way between the seafloor and the under surface of the ice) by a bridal attachment and rope secured at the surface (see figure below). A 15cm fin was attached to the base of the instrument for all deployments. In shallow locations the instrument was positioned so that it could not hit the seafloor throughout the lowest tidal cycle during the deployment. The profile interval was set to record every 900 seconds (15min) for a period of 120 seconds (2min). All instrument settings and recording details are contained in the hdr files saved in each data folder. Start and end dates and times are set out in the “current meter deployment details” spreadsheet.

The files described here are the Main Hawaiian Islands (MHI) Atlantis Ecosystem model input files used in for testing CMIP6 climate scenarios developed by main Hawaiian Islands ROMS. These input files were used to run forecast simulations under three different CMIP6 climate change scenarios: low-emission (SSP1-2.6), moderate-emission (SSP2-4.5), and high-emission (SSP3-7.0). Files included are parameter (.prm), initial conditions (.nc), and land-based source pollutants (LBSP) forcing files. The parameter files include a run file, biological parameters, forcing parameters (list climate and pollution forcing files), harvest parameters (fishing mortality), and physics parameters. The LBSP forcing files are time series files representing spatial deposition of nutrients and sediments from land to the nearshore regions covered by Hawaii Atlantis. In recalibrating the current model based on updated climate forcing files (ROMS projections), the parameter and initial conditions files have been adjusted since initial model development. The ROMS projections used to force Hawaii Atlantis are not included in this data set, as they are from a different project. Hawaii Atlantis was initially developed at PIFSC and further details regarding the model, as well as outputs of a model run based on older inputs, are hosted as InPort catalog item 55245. The LBSP forcing files hosted here were developed based on Ocean Tipping Points project data as part of initial model development.
