MarE3 (formerly known as CDEX) owns and operates the Scientific Drill Ship Chikyu. Starting with the Integrated Ocean Drilling Program (IODP) in 2006, and then continuing with the International Ocean Discovery Program (IODP) from 2013, DV Chikyu has contributed to the continuing evolution of scientific ocean drilling. More about the history of scientific ocean drilling can be found here:
The data presented on this website have been collected from DV Chikyu's scientific ocean drilling cruises in support of IODP operations since 2006. These data are all publicly available; however, we ask that you register a free account before downloading any data. This is so we can see what uses these data are being put to. Anyone can open an account, so data can be used by the general interested public, students, educators, researchers, and media representatives.
There is one exception to the open data policy: all expeditions have a 1 year moratorium period during which they are accessible only to the expedition scientists. After this period ends, the data are opened to the public.
Questions about how to use these data, or anything related to these data, or their availability, can be directed to: (mare3-feedback@jamstec.go.jp).
IODP Sample, Data, and Obligations Policy and Implementation
(Quoted from the current version of the IODP Sample, Data and Obligations Policy and Implementation Guidelines, available here: http://iodp.org/policies-and-guidelines).
Approved by JOIDES Resolution Facility Board: 15 May, 2018 Latest Revision: 6 May, 2018
General Principles
The goal of this policy and guideline is to ensure open and transparent access to samples and data from the International Ocean Discovery Program (IODP), the Integrated Ocean Drilling Program (IODP), the Ocean Drilling Program (ODP), and the Deep Sea Drilling Project (DSDP) for scientists, educators, museums, and outreach officers. In return, recipients of IODP samples or data incur obligations on their use and reporting of the science outcomes from research based on these samples or data. The use of all core materials, samples, and data are under the auspices of the IODP Curators and the IODP Curatorial Advisory Board (CAB). Specifically, the International Ocean Discovery Program, and encompassing all previous incarnations of scientific ocean drilling, ensures:

The entire input sentence is called a "query". There are two types of queries: "partial match queries" and "exact match queries".
A partial match query is a query used to search for data that includes specified keywords. In a partial match query, enter the keyword(s) you wish to search for as is.
Correct partial match queries
// Search for data including "aaa". // For example, "aaa", "aaaaa", "bbbaaa123", etc. will match. aaa // Search for data including "1B". // For example, "C0001B", "C0011B", "C0021B", etc. will match. 1B
For partial match queries, "upper case alphabet," "lower case alphabet," "numbers," "underscore," and "percent" can be used.
Incorrect partial match queries
// "あ" cannot be used in keywords.
aaaあああaaa
// "(" cannot be used in keywords.
// Can be used in the grouping described below.
aaa((()))aaaAn exact match query is a query used to search for data that matches specified keywords. In an exact match query, the keywords to be searched for are enclosed in " ".
Correct exact match query
// Search for data matching ""aaa"" // For example, "aaaaa", "bbbaaa123", etc. will not match. "aaa"
For exact match queries, "upper case alphabet", "lower case alphabet", "numbers", "underscore", "percent", "round brackets", and "space" can be used.
Incorrect exact match query
// "あ" cannot be used in keywords. "aaaあああaaa" // not enclosed in " " "aaa
Partial match queries and exact match queries cannot be mixed.
Incorrect query
// aaa is a partial match query and "bbb" is an exact match query. aaa "bbb"
Complex conditions can be expressed by separating keywords with separators. There are two types of separators: "AND separators" and "OR separators".
A space separating keywords is called an AND separator. By separating keywords with an AND separator, the condition "XX and XX" can be expressed.
Correct AND separator
// Partial match queries and AND separators // The following means "includes aaa and includes bbb and includes ccc" aaa bbb ccc // Exact match queries and AND separators // The following means "exact match to aaa and exact match to bbb and exact match to ccc" "aaa" "bbb" "ccc" // Any number of spaces in the AND separator is acceptable, as long as it is more than one. // The following also means "includes aaa and includes bbb and includes ccc". aaa bbb ccc
Correct, but perhaps not as intended
// Using spaces within keywords in an exact match query does not make it an AND separator // The following means "exact match to 'a a a'". "a a a"
A vertical bar separating keywords is called an OR separator. By separating keywords with an OR separator, the condition "XX or XX" can be expressed.
Correct OR separator
// Partial match queries and OR separators // The following means "includes aaa or includes bbb or includes ccc". aaa|bbb|ccc // Exact match queries and OR separators // The following means "exact match to aaa or exact match to bbb or exact match to ccc". "aaa"|"bbb"|"ccc" // A space may be included before or after the OR separator. // This space is simply ignored. // The following also means "includes aaa or includes bbb or includes ccc". aaa | bbb |ccc
Incorrect OR separator
// OR separators cannot be consecutive aaa|||bbb
Grouping is a term used to express a rule for combining terms by enclosing keywords in round brackets. Grouping is allowed at only one level and cannot be nested.
Correct grouping
// The following means "'includes aaa or includes bbb' and includes ccc" (aaa | bbb) ccc // The following means "includes aaa or 'includes bbb and includes ccc'" aaa | (bbb ccc) // Can be grouped multiple times if not nested. (aaa bbb) | (ccc ddd)
Incorrect grouping
// Nested grouping is not allowed ((aaa bbb) | ccc) ddd
When a category name (e.g. Resistivity, Bit, Ring, ...) is specified as a keyword, it is expanded as a keyword corresponding to the category name. For example, "Bit" has the same meaning as "(RBIT|ABR)".
Correct query
// Bit is expanded, and becomes "'includes RBIT or includes ABR' and inclules aaa"
Bit aaa
↓
(RBIT | ABR) aaa
// Bit is expanded, and becomes "'exact match to RBIT or exact match to ABR' and exact match to aaa"
"Bit" "aaa"
↓
("RBIT" | "ABR") "aaa"Expanded keywords implicitly create a group, so expansion cannot be used within a group.
Incorrect Query
// Expansion creates nested groups (Bit aaa) | bbb ↓ ((RBIT | ABR) aaa) | bbb
