There are a number of different core types in the OSU-MGR collections. Below is a brief guide to help in deciding what type of samples to request. There are additional coring devices not listed below. Please contact with any further questions.

Piston CorePCUp to 30 m in lengthLongest records, surface sediments lost
Jumbo Piston CoreJCSame as PC but larger diameterLongest records, surface sediments lost
Trigger CoreTCSame deployment as associated PC/JC but shorter core (maximum 3 m in length)Likely better recovery of surface sediments
Gravity CoreGCUp to 12 m in lengthLikely better recovery of surface sediments
MulticoreMCShorter record- cores are maximum 60 cm in lengthBest recovery of surface sediments
Kasten CoreKCUp to 4 m in length, rectangular core collects larger volume than gravity coreGreater volume of sediment recovered
Box CoreBCRecovers large volume of upper sediments (60 cm max)Minimal disturbance of upper sediments
VibracoreVCVibrating corer recovers up to 6 m in lengthUsed to sample sandy sediments
GrabGSimple scoopSurface sediments only, no stratigraphy recovered
Push CorePUManually driven core used to sample marsh sediments where no other coring device is an optionVariable recovery and core condition
DredgeDChain net dragged along the seafloorChips off and catches rocks from a swath of the seafloor
DiveDROV-deployed samplersGrab samples or small cores collected with ROV arm
