These pages contains MIT-MSEAS simulations of ocean dynamics and ocean observing assets for the Southern California region. The simulations focus on different periods and ocean regimes. The ocean observing assets simulated are isobaric floats, isopycnal floats, and ocean gliders.
Period 1: July 24 to August 6, 2018
Simulations of Ocean Physics
In the table, we provide animations of vorticity, temperature, salinity, and Sigma-T at 150m and 200m depth for Period 1.

Simulations of Float Transports over Time
All floats are simulated until August 6, 2018 00Z. Below are examples of a single release of (many) floats on a single day (July 24, 2018), multiple days (daily releases), and finally, animations of such float trajectories.
- Single-day release: Daily subsurface isobaric float locations over time for a single July 24, 2018 release date, released at 150m and 200m depths
- Multi-day releases: Daily subsurface isobaric float locations over time, released at 150m on different days from 2018-07-24 to 2018-07-31
- Next, we show the initial 2018-07-24 00Z and final 2018-08-06 00Z locations of isobaric floats released at 150 m on 2018-07-24 00Z around the Santa Rosa and San Miguel islands, colored by their starting latitude (left two panels) and final temperature (right two panels).

Simulations of Gliders of Different Horizontal/Vertical Speeds
All simulated gliders start sailing and collecting simulated data on July 24, 2018.
