Study on Acoustic Variability Affected by Upper Ocean Dynamics in South Eastern Arabian Sea

Earth and Space Science, Volume 11, Issue 11, November 2024.
Abstract The influence of upper ocean dynamics on the acoustic field in the South Eastern Arabian Sea (SEAS) is studied using in situ oceanographic/acoustic measurements from a moored buoy, along with satellite‐derived and climatological data sets. Upper‐ocean variability at the site is quantified using Mixed Layer Depth (MLD), Isothermal Layer Depth ...

Significance of Various Sensing Mechanisms for Detecting Local and Atmospheric Greenhouse Gases: A Review

Advanced Sensor Research, Volume 3, Issue 2, February 2024.
The greenhouse effect is an effector by which the Earth has encountered warming temperatures, “global warming”, whereby, escalating global temperatures are correlated to excessive atmospheric natural and synthetic GHGs, which absorb IR from the Earth.

Ionospheric Disturbances Generated by the 2015 Calbuco Eruption: Comparison of GITM‐R Simulations and GNSS Observations

Space Weather, Volume 22, Issue 2, February 2024.
Abstract Volcanic eruptions provide broad spectral forcing to the atmosphere and understanding the primary mechanisms that are relevant to explain the variety in waveform characteristics in the Ionosphere‐Thermosphere (IT) is still an important open question for the community.

Sampling mobile oceanic fishes and sharks: implications for fisheries and conservation planning [PDF]

, 2017
Tuna, billfish, and oceanic sharks [hereafter referred to as ‘mobile oceanic fishes and sharks’ (MOFS)] are characterised by conservative life-history strategies and highly migratory behaviour across large, transnational ranges. Intense exploitation over
