Summary of Field Work: |
This is a continuation of US-India-Sri Lanka collaboration collaboration. R/V Roger Revelle made port calls from Chennai and Colombo in 2013, 2015, and 2016. The R/V Thomson will continue work this year in June/July 2018, making measurements in Sri Lankan (2018 only) and international waters. During these cruises US, Indian, and Sri Lankan scientists worked together to measure air-sea fluxes, near-surface, and ocean boundary layers for improved prediction of the monsoon at the intraseasonal time scale.
This work needs to occur during the summer monsoon (mid-June through mid-September) and should span 60 days with one to two port calls (i.e., two 30 day legs). We are now organizing a dual operation with the C130 group from Biloxi, MS. Aircraft operations are limited to June 10 to June 24 2019, so we are requesting a start date of June 10.
Due to logistical reasons shipping of gear in and out of India has been problematic. We will likely need to have a short port call in Sri Lanka at the end of the cruises. For example, Leg 1 could be in and out of Sri Lanka, Leg 2 could be in and out of India, and then a final stop in Sri Lanka would be needed to remove and ship gear. An alternate schedule that may work would be to have Leg 1 in and out of Sri Lanka, and Leg 2 mobilizing from India and demobilizing from Sri Lanka. These details will need to be facilitated with ship scheduler, ONR, PIs and partner countries. |
|
Summary of Facility Requirements: |
We require a global class vessel (e.g., Thomson or Revelle) with CTD/rosette, ADCP, multi-beam/echosounder, standard atmospheric meteorological sensors, sufficient deck space/A-frame for mooring deployments/recoveries, and van space for containers. We may need to add additional atmospheric flux sensors to forward mast. |
|
Summary of other requirements and comments: |
The project start and end dates reflect the requested start and end times for the cruise. As per above, dual operations with the C130 group are limited to June 10-June 24, 2019. |

Dates to Avoid: |
C130 operations are limited to June 10-24th 2019, cruise needs to overlap with this period and occur within the summer monsoon. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The global class ship is requested due to the anticipated size of the science party. This project involves multiple PIs and partnerships within Sri Lanka and India. As part of these partnerships we include a large number of students and post docs from these countries as part of the science team.
The science aim of this project is to look at intraseasonal oscillations (ISO) in the monsoon. The time scale of the ISO is long-- nominally 45 to 60 days. In order to observe the phenomenon of interest and allow for time to recover moorings and other drifting assets, we are requesting 60 science days. |

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
We will need to have one leg in and out of Colombo and a second leg in and out of Chennai. A final stop in Sri Lanka is needed to offload and ship science gear. Please refer to the 2014 (Revelle), 2015 (Revelle), 2018 (Thomson) for previous examples of port calls related to the ASIRI (2014, 2015) and MISO-BOB (2018) work. |
