Science Objectives | |
The primary objective of this proposal is to collect a suite of glassy volcanic rocks from the Mid Atlantic Ridge, measure the full suite of volatiles, major elements, trace elements, and isotopes, and evaluate their geochemical variability with respect to their geological setting. An ROV or submersible is required for this project because the seafloor eruption style will be critical in relating the samples to local and regional tectonics. We propose a field program to the MAR between 13°30’ and 14°05’N that makes use of existing sonar data between 13° 15’N and 13° 50’N (Mallows and Searle, 2012), the Alvin, Sentry and the WHOI TowCam. The use of Alvin will allow us to collect well located samples and to determine if vesicularity and volatile abundances relate to their geologic setting and at what scale (i.e. segment wide, 'tectonic' vs. 'magmatic', adjacent to detachment faults, etc.). This will include sampling on the segment scale (e.g., magmatic segment center and detachment faulted terrain), and the local scale related to seamounts/source vents, lava flow size and origin, and proximity to detachment faults. Existing data from dredge samples do not allow evaluation of these factors. The use of Alvin will also allow controlled sampling of glassy samples, not just with respect to geologic setting, but to ensure preservation of the volatiles. Selected glassy samples will be collected in anaerobic sea-floor samplers that retain (some) sea floor pressure and temperature, thus minimize air contamination (Kurz and Curtice, 2009), reducing the reliance on post-analysis corrections. These vessels will also permit collection of any gas exsolved at the surface because the samples can be kept immersed, allowing them to warm slowly (exsolved gases will then be collected in copper tubes). This will reduce the uncertainties associated with estimates of “pre-degassing” volatile contents. In addition to existing sonar data, we will use AUV Sentry make local high-resolution bathymetry and sonar maps north of 13ËÂÂÂÂÂÂÂÂÂÂÂÂÂÂ50 (i.e., the magmatic segment) to define the geologic context of those samples. TowCam will be used for reconnaissance imaging and characterization to help define Alvin and Sentry dive targets. | |
Science Activities | |
| Alvin diving- includes observations, imaging (video and still imaging), mapping, rock sampling, push cores, possible small Niskin water sampling, and Ti-major samplers for possible use if hyx vents are encountered Sentry AUV diving (mostly night time) TowCam night time surveys shipboard multibeam surveys possible dredging as a contingency possible CTD as a contingency (to be ready to use but stored on 01 deck) rock processing in main lab rock sawing in wet lab | |
