IIOE-2 Cruise No.EP1-1, 4 December, 2015 - 22 December 2015, Goa, India - Mauritius. ORV Sagar Nidhi Cruise 105 (04 – 22 December 2015) International Indian Ocean Expedition - 2, First Expedition.SN-105 is the first cruise conducted as a part of the Second International Indian Ocean Expedition (IIOE-2). IIOE-2 was launched as well as SN-105 was flagged off at Goa by the Minister of State for Science and Technology, Govt. of India on 4 December 2015. The major objective of this multidisciplinary observational expedition is to understand the structure of water masses in the western Indian Ocean along 67E and possibly assess the difference in their characteristics with respect to the measurements made during IIOE. The other objective of the cruise is to understand the physical-chemical-biological characteristics in the equatorial Indian Ocean and their interrelationships. The major observational objectives are to map the hydrography in the upper 1000m where the Red Sea, Persian Gulf and Arabian Sea High Salinity water are known to be present, collect water samples to determine chemical, biological and optical parameters.

IIOE-2 Cruise No.EP2-1, 23 January, 2016 - 08 February, 2016, Chennai, India - Chennai, India. Sagar Kanya Cruise in Bay of Bengal (SK 326) 23 January - 08 February, 2016. Summary of the cruise report, 5th Research Cruise under Ocean Mixing and Monsoon (OMM) Experiment.Sagar Kanya started sailing from Chennai port from 23rd January on a 17 day cruise. Total science crew in this cruise (SK 326) is 21 which include scientists and students from several Indian research labs and academic institutes. Mr. Jeff Lord and Mr. Emerson Hasbrouck of Woods Hole Oceanographic Institute (WHOI, USA) also participated in SK 326 for a WHOI mooring recovery which was deployed in November 2014 in a Sagar Nidhi cruise. SK 326 is the 5th cruise under the Ocean Mixing and Monsoon (OMM) program, the other four were conducted onboard Sagar Nidhi (SN 82, SN88, SN 14/2014, and SN100). Main objectives of the 17 day cruise are a) Recovery of the Woods Hole Mooring b) Extensive upper ocean survey of the Northern Bay of Bengal c) Deployment & Recovery of Lagrangian float and deployment of argo floats d) NIOT's 3 mooring operations (Deployment & Recovery of BD11 and Recovery of ITBS).

IIOE-2 Cruise No.EP3-1, 13 February, 2016 - 14 March, 2016, Chennai, India - Port Blair, India. ORV - Sagar Kanya IIOE-2 Cruise Report, Cruise No. SK-327 (13th Feb 2016 – 14th Mar 2016).This cruise will be dedicated to the recovery and deployment of RAMA Buoys & NIOT Omni & Tsunami Buoys. The moorings are a part of the Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA). This array is under development as part of a multi-national effort to provide data essential for monitoring, understanding, and predicting basin scale ocean-atmosphere variability such as the Asian monsoon, the Indian Ocean Dipole, and the Madden-Julian Oscillation

IIOE-2 Cruise No.EP3-2, 09 November, 2016 - 17 December, 2016, Chennai, India - Chennai , India. ORV - Sagar Kanya Cruise Report, Cruise No. SK - 335 (09th November – 17th December, 2016).This cruise will be dedicated to the recovery of three and deployment of two deep ocean RAMA moorings, and the recovery of five deep ocean subsurface (Acoustic Doppler Current Profiler) ADCP moorings. The moorings are a part of the Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA). This array is under development as part of a multi-national effort to provide data essential for monitoring, understanding, and predicting basin scale ocean-atmosphere variability such as the Asian monsoon, the Indian Ocean Dipole, and the Madden-Julian Oscillation. (Conductivity, Temperature and Depth) CTD operations were conducted after every RAMA and ADCP Mooring buoy deployment/retrieval locations.

IIOE-2 Cruise No.EP12-1, 15 April, 2017 - 03 May, 2017 Kochi, India - Goa, India. Dust induced Primary Productivity and N2 fixation experiments in the Arabian Sea.Oceans act as a major sink for anthropogenic CO2 through primary production. The Arabian Sea (area ~6.2 × 106 km2) covers only about 1% of the global ocean surface but contributes up to 5% of the global marine primary production, partly due to high influx of ‘new’ nitrogen via diazotrophic N2 fixation. Iron, whose main source in the ocean is atmospheric transport of dust, is an essential nutrient for sustaining N2 fixation. Despite being in the vicinity of the Thar desert on the east and the Arabia desert on the west, the Arabian Sea has been projected to be an HNLC (high nutrient low chlorophyll) region
