Science objectives

Training a cohort of early career scientists in deep submergence cruise planning and leadership.
Conducting observations and collection of samples at seafloor methane seep and coral community sites.
Acoustic mapping of the seafloor and water column.

Key training objectives include providing experience in:

i. collaborative, multidisciplinary and interdisciplinary research and proposal strategies for deep-submergence science

ii. leadership in cruise and dive/mission planning and execution

iii. integration of instrumentation with Alvin/Sentry/other deep-submergence assets

iv. telepresence research and communication: seafloor-to-ship-to-shore

v. data management, sharing, reporting

vi. science communication

 

Key scientific objectives include:

i. Investigating the linked biological, chemical, physical, and geological processes that are manifest at seafloor methane seep and coral community sites

ii. Constraining the spatial and temporal extent of those processes. 

(More detailed objectives to be determined in consultation with cruise participants)

 

Science Activities

Alvin dives with collection of biological and geological samples
