A partnership between NOAA, CARICOOS, University of Miami, University of Puerto Rico, and IOOS
AOML's Physical Oceanography Division, the Caribbean Coastal Ocean Observing System (CARICOOS), and NOAA's Integrated Ocean Observing System (IOOS) are leading a multi-institutional effort that brings together the research and operational components within NOAA and the university community to implement and carry out sustained and targeted ocean observations from underwater gliders in the Caribbean Sea and southwestern tropical North Atlantic Ocean. The upper ocean thermal structure in this region has been linked to rapid intensification of tropical cyclones, and to the seasonal Atlantic hurricane activity. However, there are only few (<300) upper ocean thermal observations carried out per year in this region.
Goal: The goal of this work is to enhance our understanding of air-sea interaction processes during hurricane force wind events. In order to accomplish this goal, the network of hurricane underwater gliders was implemented to:
The work carried out by this project provides between 6,000-10,000 profile observations of each observed parameter (e.g temperature, salinity, dissolved oxygen, chlorophyll concentration). AOML-CARICOOS Underwater Gliders are officially part of the NOAA Hurricane Research Division tropical Atlantic Hurricane Field Program.

11/01/2017 - Missions 15, 16 and 17 Start: The three gliders (SG610, SG630, and SG635) were successfully recovered marking the completion of the 2017 NOAA/AOML Hurricane Underwater Glider Deployment.
07/14/2017 - Missions 15, 16 and 17 Start: Three gliders (SG610, SG630, and SG635) were deployed in the Caribbean Sea and Tropical North Atlantic, marking the start of underwater glider missions in support of the 2017 Hurricane Field Observations Program
03/11/2017 - Missions 13 and 14 Completed: Two gliders (SG610 and SG630) were successfully recovered in the Caribbean Sea. Issues with the gliders caused a premature ending for these missions
03/07/2017 - Missions 13 and 14 Starts: Two gliders (SG610 and SG630) were deployed in the Caribbean Sea.
11/10/2016 - Missions 9, 10, 11 and 12 Completed: Two gliders (SG609 and SG630) were successfully recovered in the Caribbean Sea on November 10, 2016. The recovery marks the successful completion of AOML's fifth underwater glider mission during the 2016 Hurricane Season.
11/02/2016 - Gliders SG547 and SG610 recovered: Two gliders (SG547 and SG610) were successfully recovered in the North Atlantic on November 2d, 2016.
07/22/2016 - Missions 9, 10, 11 and 12 Starts: Two gliders (SG609 and SG630) were successfully deployed in the Caribbean Sea on June 21, 2016. The deployment marks the beginning of the 2016 Atlantic Hurricane Season deployment. Two more gliders are expected to be deployed in the tropical North Atlantic as part of the Hurricane season operations. AOML-CARICOOS Underwater Gliders are officially part of the NOAA Hurricane Research Division tropical Atlantic Hurricane Field Program.

During these missions, over 2,600 temperature, salinity, and dissolved oxygen profiles were collected.
08/11/2015 - Science highlight: In a recent manuscript by Domingues et al. (2015), observations collected by glider SG609 before, during, and after the passage of Hurricane Gonzalo (2014) were analyzed to improve our understanding of the upper ocean response to hurricane winds. this study is that salinity potentially played an important role on changes observed in the upper ocean; a near-surface barrier layer likely suppressed the hurricane-induced upper ocean cooling, leading to smaller than expected temperature changes. Additional details can be found here [pdf].
