Poseidon-viewer cutout, section, and station functions
Wondering what those icons are at the top of the Poseidon-viewer? New sample Jupyter notebooks are now available at the Poseidon-share repo that explain them. The buttons allow you to select points (like oceanographic stations), polylines (like sections), or polygons (cutouts). The data can then be imported into Jupyter notebooks and used to make calculations […]
LLC4320v2 Dataset is Coming…
The new and improved LLC4320v2 dataset is being transferred to SciServer and transformed for public access under the Kraken domain. The LLC4320v2 run is a global-ocean-ice-river-tides simulation. Like LLC4320, it uses a 1/48° horizontal grid (about 2km grid spacing). Key features are: – Newer bathymetry (GEBCO 2025) – Non-linear free surface and z* vertical coordinates […]
DYAMOND coupled ocean-atmosphere simulation available
The DYAMOND simulation (aka GEOS/ECCO C1440-LLC2160) is a very high resolution coupled ocean-atmosphere run. It uses the MITgcm ocean model (2–4 km grid, 90 levels) and the NASA Goddard Earth Observing System (GEOS) atmosphere model (7 km grid, 72 levels). The simulation lasts 14 months starting 20Jan20. For access instructions, see here. And for the […]
Full LLC4320 dataset available
LLC4320 is a 1km resolution global ocean circulation simulation spanning the period September 2011 to November 2012. This 4 PB dataset is now available on SciServer. For access instructions see here.
Poseidon Data Access Portal under construction
The multi-petabyte storage cluster for the Poseidon project is being tested by the project team. The system consists of 15 storage nodes running ceph and a variety of NVMe solid state fast storage device options. Compute nodes for data analysis are also being procured. The system is powered up and undergoing testing. Several system components […]
