• Poseidon Project at 2024 Ocean Sciences Meeting February 26, 2024
  Tom Haine and Wenrui Jiang led a Town Hall meeting at the Ocean Sciences Meeting entitled “Democratize the Data: A New Way to Analyze Ocean Models”. Take the survey on next-generation benchmark circulation models. And watch this space for results from the survey… Abstract: Ocean circulation models running on the latest supercomputers can cover the […]
• OpenOceanCloud Working Group February 19, 2024
  Tom Haine is a member of the OpenOceanCloud Working Group (OOCWG), which is aligned with the Poseidon Project. The main goal of the OOCWG is to help the ocean science community, federal agencies, and research institutions align and coordinate a shared vision for data-proximate cloud computing to support research and education. To achieve this goal, […]
• Seaduck: A python package for Eulerian and Lagrangian interpolation on ocean datasets December 20, 2023
  Numerical simulations of the Earth’s oceans are becoming more realistic and sophisticated. Their complex layout and sheer volume make it difficult for researchers to access and understand these data, however. Additionally, most ocean models, mostly finite-volume models, compute and calculate spatially-integrated properties, such as grid-cell averaged temperature or wall-integrated mass flux. On the other hand, […]
• How fluid tracers spread: New paper on shear dispersion October 23, 2023
  Assistant Research Scientist and Poseidon Project team member Miguel Jiménez-Urias has published a paper on the dispersion of passive tracer. The title is “On the non-self-adjoint and multiscale character of passive scalar mixing under laminar advection” and the paper appears in the Journal of Fluid Mechanics. Miguel writes in the paper’s Abstract: “Except in the […]
• NSF CSSI PIs Meeting September 29, 2023
  The Poseidon Team presented a poster at the 2023 NSF CSSI PIs’ Meeting in Houston, TX. You can see the poster here.
• Poseidon-viewer LLC4320 visualization tool launched September 1, 2023
  The Posiedon-viewer tool is now available for public use. Browse the global 1-km resolution LLC4320 model solution with ease. The Poseidon-viewer is interactive and responsive. Run it standalone here, or from a SciServer Oceanography (integrated viewer) container.Enjoy exploring!
• Seaduck interpolation software computes Lagrangian trajectories August 1, 2023
  The Poseidon team has published a new interpolation software tool. Graduate student Wenrui Jiang has led the effort and calls the package Seaduck. Seaduck is a flexible python tool that interpolates data from ocean datasets from both Eulerian and Lagrangian perspective. For example, it can efficiently compute Lagrangian particle trajectories in the Poseidon ocean circulation […]
• Poseidon Data Access Portal under construction April 21, 2023
  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 […]
• Daily ECCOv4r4 data is now online March 28, 2023
  The ECCO global state estimate is an important ocean reanalysis dataset. It blends a dynamical ocean circulation model with several hundred million observations from satellites and in situ instruments for the period 1992–2017. The monthly-average ECCOv4r4 data has been available for some time on SciServer. Now the daily-average dataset is online. To access the data […]
• New LLC4320 data January 21, 2023
  The LLC4320 global 2km resolution dataset has been extended. The new fields include the air/sea forcing data, sea ice, and vertical speed. Remember, the LLC4320 data currently on SciServer are just a 10-day test set. The full dataset is coming soon…
