Dataset for: The role of open ocean and coastal tidal currents in the maritime migration to Sahul, ca. 65,000–50,000 years ago.

This dataset supports the thesis: Kuijjer, E.K. (2020) 'The role of open ocean and coastal tidal currents in the maritime migration to Sahul, ca. 65,000–50,000 years ago'. PhD thesis, University of Southampton. Kuijjer_2020_Data_Chapter_4: This folder contains the results of Ariane calculations, as described in Chapter 4 of the thesis. Lagrangian particle tracking algorithm Ariane (http://stockage.univ-brest.fr/~grima/Ariane/) was applied to a multi-year hindcast of ocean general circulation model NEMO (ORCA12 configuration; https://www.nemo-ocean.eu/) to calculate trajectories of particles from different locations in the region between Sunda (Southeast Asia) and Sahul (Australasia). Included in this dataset are results for each month in which particles were released (January and July, 1989-1998). Results can be found in traj.txt, which includes: particle no., longitude, latitude, depth (m), time (days), temperature, salinity, density. Kuijjer_2020_Data_Chapter_5: This folder contains the results of the MIKE21 FM simulations for the month January 2010, as described in Chapter 5 of the thesis. MIKE21 FM coastal modelling tool (Danish Hydraulic Institute (2016) MIKE 21 & MIKE 3 Flow Model FM, Hydrodynamic and Transport Module, scientific documentation. Available from: www.mikepoweredbydhi.com [Accessed 7 August 2016]) was used to explore tidal dynamics north of Australia under seven mean sea level scenarios: 0 m, -25 m, -50 m, -75 m, -100 m, -125 m, and -150 m. Included here, in netcdf format, are X (longitude), Y (latitude), TE (triangulation matrix), Max_SP (maximum current speed, January 2010), and Max_TR (maximum tidal range, January 2010). For more details, please see Chapter 4-5 of the thesis, and the readme file included with the dataset. The data can be viewed and analysed using software such as MATLAB (http://www.mathworks.com).
