Cruise Inventory Information

Long name	RRS James Cook (740H) cruise JC113
Short name	JC113
Objectives and Narrative	The overall goal of JC113 is to improve our understanding of how hydrothermal circulation couples the ocean and lithosphere. To achieve this goal we collected heat flow measurements on the southern flank of the Costa Rica ridge flank. The principal science objectives are to: 1. Understand the thermal characteristics and heat transfer from the crust to the ocean between the Costa Rica Rift and IODP Hole 504B 2. Provide a process-based understanding of how crustal hydrothermal circulation impacts deep ocean circulation in the Panama Basin 3. Understand linkages among the shallow structure of the oceanic crust, its evolution, and heat transfer.

Cruise Inventory Datasets

Geology and geophysics
Other geological/geophysical measurements	Quantity: number of stations = 1 Description: Heat flow station PB01, located within a sediment pond of the Panama fracture zone. Used to test the heat flow instrumentation over a region where swath bathymetry and sub-bottom profiling data had been previously collected. No problems experienced during data collection. 18 measurements.
Other geological/geophysical measurements	Quantity: number of stations = 1 Description: Heat flow station PB02. Northernmost station, positioned where sediment cover was thought to be a minimum value to capture well-ventilated hydrothermal circulation. 19 measurements.
Other geological/geophysical measurements	Quantity: number of stations = 1 Description: Heat flow station PB06. Southernmost station, in the region with the greatest sediment thickness. 15 measurements.
Other geological/geophysical measurements	Quantity: number of stations = 1 Description: Heat flow station PB04, positioned in a region of relatively more extensive but thin sediment cover. 15 measurements.
Other geological/geophysical measurements	Quantity: number of stations = 1 Description: Heat flow station PB05, positioned adjacent to previously collected data with the specific goal of assessing lateral variability. 7 measurements.
Other geological/geophysical measurements	Quantity: number of stations = 1 Description: Heat flow station PB03, positioned in a region of sparse sediment cover similar to PB02, over a region of increasing seafloor depth. 11 measurements.
