D/V Chikyu and Scientific Drilling
Drilling Vessel (D/V) “Chikyu” (Japanese for “the Earth”) is the largest scientific drilling vessel in the world, with a length of 210 m, width of 38 m, draft of 9.2 m and a gross tonnage of ca. 57,000 metric tons. D/V Chikyu is also one of the world’s deepest drilling vessels, and has been fitted with riser equipment, technology developed by the oil industry to permit deep sub-seafloor drilling - in Chikyu's case, through 7000 meters of crust below the seabed while floating in 2500 meters of water. In riserless mode, Chikyu has drilled about 1000 meters below the seafloor in nearly 7000 meters of water.
Laboratories, crew accommodations and navigation facilities, and a helideck on the bow, occupy one-third of the vessel. The rest of the ship is for the drilling floor and drilling equipment. The total area of the lab spaces are about 2300 m² on four decks. 200 people, roughly 50 scientists, 50 technicians, and 100 ship and drilling crew, can work at sea for scientific drilling expeditions.
This wiki was created to help expedition scientists organize and prepare for their work at sea more efficiently, introduce lab facilities and equipment, general ship layout, general rules, and other equipment available aboard D/V Chikyu. This wiki also provides a guide to the kinds of chemicals needed for research and available aboard D/V Chikyu.
Expeditions & Logistics
This section describes how to apply to sail on scientific expeditions, what you need to do once your application to sail has been accepted, and what kind of logistical preparations you will need. This section also describes how to ship baggage and scientific equipment to and from D/V Chikyu, and other information on boarding/departing ship.
Welcome Aboard Chikyu
This section describes what you'll need to prepare for, and what to expect from, your life aboard Chikyu. Please refer to this page when planning your expedition packing. Information about daily life, safety information, and "how to get along" with your fellow scientists and crew members can all be found here.
Working on Chikyu
This section describes the ship and Laboratory section. Detailed information about the different laboratory deck layouts and brief descriptions regarding the facilities available on each deck can be found here.
IODP Measurement & Policies
Shipboard measurements for IODP expeditions are categorized as either standard or optional measurements based on the Chikyu IODP policy. This section describes the Chikyu IODP measurements as well as other IODP policies relating sample requests, publication, 3rd party tools, etc.
This section comprises a list of all chemicals provided aboard D/V Chikyu. Please check this list when making your research plans for the expedition. If you require chemicals that are NOT on this list, please contact the Expedition Project Manager (EPM) for your expedition.
Depending on the chemicals needed, special order forms and permission may be required.
The Sample and Data Policy document describe how to request and use data and samples from IODP expeditions. Please check the Lab Measurement & Equipment section first.
To make a sample request for a specific expedition, please visit the SDRM website and request an account. Fill out the form as requested, and create your account. You will be making a request for a future expedition, so please click the proper radio button and select the correct expedition. There is a short video presentation describing how to make requests.
