Description

This dataset provides dates and locations of colonization sampler deployments and recoveries from East Pacific Rise (EPR) deep-sea vents, 1998-2017.

Methods & Sampling

Dataset acquisition description

Colonists were collected on experimental surfaces (sandwiches) constructed from six 0.7-cm-thick Lexan plastic plates separated by 1 cm spacers, creating a lattice 10 cm on a side (Bayer et al, 2011; note in 1998 colonists were collected on basalt blocks). Sandwiches were deployed and recovered by the submersible Alvin. Deployment durations were 4, 2, and 11 months respectively for the recoveries at 9, 11, and 22 months after an eruption that took place in January 2006. The thermal environment at the base of each sandwich was measured with the Alvin temperature probe on deployment and recovery for ca 1–2 min until a clear maximum value was obtained. Habitat chemistry was measured at 11 and 23 months.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing Notes:
version 1 [2018-03-30]
- added conventional header with dataset name, PI name, version date
- re-formatted date from d-Mon-yy to yyyy-mm-dd

version 2 [2020-08-06]:
- includes new row for 1998 cruise, AT0319
- includes new right-most columns: monthsSinceEruption, coordinateUncertaintyInMeters, minimumDepthInMeters, maximumDepthInMeters
- renamed "End" to "eventDate".

version 3 [2020-08-24]:
- changed monthsSinceEruption on cruiseID=AT2623 from 108 to 106.

Instruments

Lexan plastic 6-plate settlement panel

Supplied Name: Lexan plastic plates/sandwiches

Supplied Description:

Instrument Type

Generic Name: Lexan plastic 6-plate settlement panel

Acronym: Colonization sandwich

Generic Description:

An artificial colonization substrate, sometimes referred to as a "colonization sandwich", that is made of 6 Lexan plastic sheets separated from each other by spacers. It is used to determine the extent of colonization and/or the diversity of settled organisms in a marine or artificial environment.

Microscope - Optical

Supplied Name: Dissecting microscope

Supplied Description:

Used to identify specimens found on the colonization plates.

Instrument Type

Generic Name: Microscope - Optical

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB05/

Generic Description:

Instruments that generate enlarged images of samples using the phenomena of reflection and absorption of visible light. Includes conventional and inverted instruments. Also called a "light microscope".

Temperature Logger

Supplied Name: temperature recorders (Hobo)

Supplied Description:

Used to track the in situ temperature during colonization at the vent zones.

Instrument Type

Generic Name: Temperature Logger

Generic Description:

Records temperature data over a period of time.
