Acoustic Observation, Identification, and Scattering Intensity Measurement of Cold Seep Based on Bubble Resonance [PDF]

open access: yesIEEE Transactions on Instrumentation and Measurement, 2022
The active “cold seep” is indisputable evidence to identify the existence of submarine gas hydrate. Due to the difference in acoustic properties between cold seep bubbles and surrounding seawater, measuring scattering intensity is a new means to detect ...

Element Variation in a Clam Shell and its Implications for Cold Seep Irregular Eruptions: Calyptogena Sp. In the Haima Cold Seep

SSRN Electronic Journal, 2022
Cold seep is characterized by methane-rich fluids released from subsurface reservoirs, and it sustains the chemosynthetic ecosystems on the seafloor. Previous studies suggest that the activity of cold seep could affect the seawater chemistry and ambient temperature.

Macro-Ecology of Gulf of Mexico Cold Seeps

Annual Review of Marine Science, 2009
Shortly after the discovery of chemosynthetic ecosystems at deep-sea hydrothermal vents, similar ecosystems were found at cold seeps in the Gulf of Mexico. Over the past two decades, these sites have become model systems for understanding the physiology of the symbiont-containing megafauna and the ecology of seep communities worldwide.

Methods for the Study of Cold Seep Ecosystems

2010
The discovery of huge subsurface reservoirs of methane in the form of gas hydrate, has fueled the interest in the associated seep ecosystems and their role as barriers against this greenhouse gas. Technological advances in high-resolution mapping and optical imaging, as well as in situ chemical analyses of the deep seafloor have helped to reveal the ...
