“…This observation on the predominance of Lepas anatifera corroborates the earlier observation made on the instrumented moored buoy sensors operated in the Northern India Ocean (Venkatesan et al, 2017). This variation in the fouling species between the earlier studies on coastal environment ( Sathpathy et al, 2010;Vedaprakash et al, 2013) could be attributed to the availability of larvae of the settling species in the local ecosystem, presence of required food, variation in the sunlight penetration over the depth, and so forth, which play a limiting factor for recruitment of many biofouling organisms. The most dominant fouling species on the buoy hull deployed in the open ocean is gooseneck barnacle of Lepas sp.…”

“…Moored marine sensors were retrieved for observation and maintenance after a period of 1 year. The sensors of all the locations and depths of deployment were observed for biofouling, and data on biofouling area coverage (% area coverage) and biofouling load (kg/sensor) were recorded, according to Vedaprakash et al (2013) and Venkatesan et al (2017). For calculating biofouling load, weight accumulated on the sensors as a result of fouling was estimated by subtracting the initial weight of the sensors from the final wet weight of sensors along with fouled organisms.…”

“…Biofouling protection of marine in-situ sensors is a challenging issue that necessitates the application of multifaceted preventive measures. Several studies have been made during the last few centuries to characterize biofouling recruitment on various metals (Vedaprakash et al, 2013;Venugopalan & Wagh, 1990), polymers (Muthukumar et al, 2011), antifouling coating (Yebra et al, 2004), engineered antifouling surfaces (Dineshram et al, 2009;Howell & Behrends, 2006), and many other materials and surfaces (Vedaprakash, 2013). Most of the studies were made on the experimental panels in the coastal region, which had shown a fouling assemblage represented by barnacles, green mussel, serpulids, macroalgae, and so forth.…”

Equipment and structures deployed in seawater and other marine environments are susceptible to marine growth. This marine biofouling is one of the critical factors that affects the measurement of continuous real-time data from the oceanographic sensors deployed for long-term observations. To understand the characteristics of biofouling on marine sensors, an investigation was conducted on sensors deployed in a moored buoy network deployed and maintained by the National Institute of Ocean Technology (NIOT) in the Arabian Sea and Bay of Bengal regions. The present paper attempts to elucidate the characteristics of biofouling on sensor components deployed at seven locations in the Bay of Bengal and five locations in the Arabian Sea, at varying depths ranging from the surface to 500-m depth. Biofouling on bare sensor surfaces and surfaces with various antifouling measures has been studied for 2 consecutive years (2015 and 2016), and the effect of antifouling measures is discussed in this paper. Among the locations studied, buoys deployed in the Arabian Sea exhibited a higher biofouling load compared to the buoys deployed in the Bay of Bengal. The study showed that the pedunculate barnacles Lepas anatifera Linnaeus, 1758, was the predominant biofouling species on these sensors. Furthermore, observations show that the use of copper- and zinc-based antifouling methods reduced the incidence of biofouling by 59% on average.

“…Due to these negative impacts, industries protect man-made structures either by using preventative measures or by removing fouling organisms, methods that can be harmful to the environment. For example, the use of antifouling paints to prevent recruitment of fouling organisms raises ecotoxicological concerns, as copper is one of the most popular antifouling components (Turner, 2010;Miller et al, 2020). Comprehensive understanding of how fouling communities evolve is an essential step toward developing more effective, safe, and sustainable approaches to mitigating biofouling of artificial substrates.…”

Biofouling of artificial substrates is a well-known phenomenon that can negatively impact offshore industry operations as well as data collection in the ocean. Fouling communities worldwide have mostly been studied within the top 50 m of the ocean surface, while biofouling below this depth remains largely underreported. Existing methods used to study biofouling are labor intensive and expensive when applied to the deep sea. Here, we propose a simple and cost-effective modification of traditional methods for studying biofouling by mounting test plates on autonomous seafloor equipment and preserving them in ethanol upon retrieval for transport to the laboratory. This method can greatly advance our understanding of biofouling processes in the deeper ocean, including fouling community biodiversity, recruitment, and seasonality. We present two case studies from the Laptev Sea and the Sea of Okhotsk in support of this method. In the first study, we looked at fouling communities on the surfaces of ocean-bottom seismometers deployed for one year in the 36–350 m depth range. In the second study, we tested metal and plexiglass (poly(methyl methacrylate) plates mounted on autonomous bottom stations and found evidence of both micro- and macrofouling after three months of deployment. Our results demonstrate that various autonomous seafloor equipment can be used as supporting platforms for biofouling studies.

“…In contrast, organic metabolites, such as acetic acid and fatty acids, can dissolve the protective calcareous deposits, which increase the polarizing current density and alter the Ca/Mg ratio [31]. The organisms' fouling marine structures are affected by several factors, including location, hydrology, season, and the properties of the substrate [32,33].…”

The Interaction of Biofoulants and Calcareous Deposits on Corrosion Performance of Q235 in Seawater

et al. 2020

An understanding of the interaction of calcareous deposits and biofoulants on the corrosion performance of steel during the fouling stage is both interesting and necessary. So, the effects of these factors on Q235 carbon steel were investigated and discussed for 20 weeks under real ocean conditions. The results indicate that calcareous deposits are favorable for the attachment of marine microorganisms. However, macroorganisms prefer adhering directly to the substrate. The generations of calcareous deposits have priority over the biofilm attachment under the condition of cathodic protection. Calcareous deposits can prevent steel against corrosion for four weeks without cathodic protection.
