... of dust over oceans is influenced by climatic factors and supports biological productivity. Anti-clockwise winds associated with tropical cyclones in the Arabian Sea are found to entrain dust and transport it mostly towards the west or in southwesterly direction (Figure 1). Cyclones over the northern Bay of Bengal aid advection of dust plumes from southwest Asia and Thar Desert over highly populated regions of the Indian Subcontinent 4 ...

... Around the globe, various nations are actively seeking alternative mining sources to meet the escalating demand for metals (Bharathi et al., 2005;Glasby et al., 2015;Naqvi et al., 2015;Sen, 2017). Certain metals, including manganese, cobalt, copper, and nickel, are believed to be found in the polymetallic nodules situated on the deep-sea oor, as illustrated in Fig. 1. ...
Deep-sea mining trials are subject to strict adherence to the international regulations for monitoring of ocean environmental data. A comparative analysis of data collected before and subsequent to the mining trials enables the assessment of the potential impact of deep-sea mining activities on the marine environment. In the realm of data collection for oceanic environments, the mooring system has been conventionally employed. This system's specifications, including length and design, are intricately governed by predetermined design criteria, with its deployment typically taking a vertical orientation. Specifically, within the context of deep-sea mining, the mooring system is effectively utilized to oversee, record, and collect mass information concerning disturbances in the water column and to the seabed. This pertains to the periods encompassing pre-exploration, exploration, and exploitation activities. The integration of various sensors, such as sediment collectors and Conductivity, Temperature, and Depth (CTD) sensors facilitates the gathering of pertinent data concerning changes in the water column and bottom disturbances. The experimental implementation of the subsurface long and short mooring within the present study is operational at an approximate depth of 5500 meters. Furthermore, the analysis encompassed in this study pertains to the determination of the mooring's ascent and descent rates. The mooring system serves as an essential tool in this endeavour, with its design and deployment intricacies well-adhering to specified criteria. The study's focus on the subsurface long and short mooring system underscores its operational depth and the meticulous configuration achieved through spatial and temporal data alignment.
... The majority of the Goan economy is dependent upon tourism (e.g., Dhargalkar et al., 1977). Mani et al. (2012) reported that Goas vast marine ecosystem is stressed by overfishing and destructive fishing practices, toxic pollutants, and climate change. Furthermore, oil spills and tar pollution add to these stresses. ...
This paper reports the impact of oil spills and tar-ball pollution on the coastal ecosystem of Goa. The factors responsible for degrading the marine ecosystem of the Goan coastline are analyzed. Uncontrolled activities were found to degrade the marine and coastal biodiversity, in turn polluting all beaches. This had a direct impact on the Goan economy through a decline in tourism. The government must adopt the necessary control measures to restore Goan beaches and the surrounding coastal areas.
