The vessel also provides a classroom for education, training, and outreach, which are key priorities of the MNF.<\/p>\n<p>RV <em>Investigator<\/em> boasts a high level of technology and advanced equipment. The vessel has a \u201cgondola,\u201d similar in shape to a small space shuttle that is mounted 1.2 m below the hull and contains a suite of acoustic mapping instruments. The position of the gondola ensures the instruments are below the layer of micro-bubbles, which cause interference created by the movement of a ship\u2019s hull through the water. The vessel also has a large moon pool that houses two drop keels which can be lowered 4 m below the hull. These carry instrumentation that includes acoustic mappers (for measuring fish and other life in the water column), a pelagic sediment profiler to produce maps of the seafloor, and Acoustic Doppler current profilers. (I had no idea what they were when I first started as vessel manager.)<\/p>\n<div id=\"attachment_505\" style=\"width: 870px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-505\" class=\"size-full wp-image-505\" src=\"\/mariner\/issue2-2020\/wp-content\/uploads\/sites\/29\/2020\/12\/investigator-pic2.jpg\" alt=\"view of vessel\" width=\"860\" height=\"286\" srcset=\"https:\/\/mainemaritime.edu\/mariner\/issue2-2020\/wp-content\/uploads\/sites\/29\/2020\/12\/investigator-pic2.jpg 860w, https:\/\/mainemaritime.edu\/mariner\/issue2-2020\/wp-content\/uploads\/sites\/29\/2020\/12\/investigator-pic2-300x100.jpg 300w, https:\/\/mainemaritime.edu\/mariner\/issue2-2020\/wp-content\/uploads\/sites\/29\/2020\/12\/investigator-pic2-768x255.jpg 768w\" sizes=\"(max-width: 860px) 100vw, 860px\" \/><p id=\"caption-attachment-505\" class=\"wp-caption-text\">David Witzke\u2019s responsibilities include managing the operation and maintenance of the ship, which has a wide range of on-board and modular laboratories and facilities.<\/p><\/div>\n<p>Over the past year \u2013 before the global pandemic \u2013 the vessel traveled 31,410 nautical miles and spent 193 days at sea visiting Antarctica, Macquarie Island, Heard Island, the Great Barrier Reef, and the Pacific, Indian and Southern oceans. Each voyage can accommodate 40 scientists and 20 crew, and has a possible range of up to 10,000 nm and 60 days. The Marine National Facility works closely with scientists two years before their time onboard the vessel to plan, manage, and execute their voyage. I get to work directly with researchers to find new and innovative ways to achieve their goals with the vessel\u2019s wide capabilities. The MNF also maintains a suite of equipment that can be employed on board and we reconfigure the vessel to meet changing requirements in the academic field. Recently, we installed a new deep-sea coring capability that allows the vessel to take seabed samples five miles below the surface of the sea.<\/p>\n<p>As the global climate continues to change and we discover the importance of our oceans, additional questions about our world will be asked. The marine research field of the maritime industry will be called upon more and more to provide sophisticated answers to help better our understanding of the marine environment and the global climate.<\/p>\n<div id=\"attachment_511\" style=\"width: 870px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-511\" class=\"size-full wp-image-511\" src=\"\/mariner\/issue2-2020\/wp-content\/uploads\/sites\/29\/2020\/12\/investigator-pic3.jpg\" alt=\"Using water camera\" width=\"860\" height=\"500\" srcset=\"https:\/\/mainemaritime.edu\/mariner\/issue2-2020\/wp-content\/uploads\/sites\/29\/2020\/12\/investigator-pic3.jpg 860w, https:\/\/mainemaritime.edu\/mariner\/issue2-2020\/wp-content\/uploads\/sites\/29\/2020\/12\/investigator-pic3-300x174.jpg 300w, https:\/\/mainemaritime.edu\/mariner\/issue2-2020\/wp-content\/uploads\/sites\/29\/2020\/12\/investigator-pic3-768x447.jpg 768w\" sizes=\"(max-width: 860px) 100vw, 860px\" \/><p id=\"caption-attachment-511\" class=\"wp-caption-text\">Investigator has drop camera and deep tow systems designed to capture high-quality video and still images from depths up to 6,000 m.<\/p><\/div>\n<p>Academic entities like Maine Maritime Academy\u2019s Corning School of Ocean Studies and the University-National Oceanographic Laboratory System are essential to marine research and will continue to provide more opportunities to mariners to work in this exciting field.<\/p>\n<p>After pushing coal, refined petroleum products, military supplies, and passengers, I have to say that I like pushing science the most.<\/p>\n<p>The Marine National Facility and the RV <em>Investigator<\/em> have given me a passion in the maritime industry I could not imagine when I was a cadet marching through the streets of Castine.<\/p>\n<p><em>For more information about RV Investigator and to view the 24\/7 livestream from the vessel, visit <a href=\"https:\/\/mnf.csiro.au\/en\/RV-Investigator\" target=\"_blank\" rel=\"noopener noreferrer\">mnf.csiro.au\/en\/RV-Investigator<\/a>.<\/em><span class=\"articleEnd\">\u2588<\/span><\/p>\n<p><span class=\"photoCredit2\">Photos: courtesy of David Witzke, courtesy of CSIRO<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>When I graduated from Maine Maritime Academy, I started a career as a Deck Officer that was typical for many mariners.
