“…Recently, lakes and estuaries have also been found to be important sources of DMS. 176 A model has been developed to simulate the seasonal patterns of DMS production and validated against nutrient concentrations, biological standing stock and other parameters. 177 Marine biogenic iodocarbon emissions are also significant for marine aerosol formation and have a key effect on global radiative forcing.…”

Recent results continue to show the general consensus that ozone-related increases in UV-B radiation can negatively influence many aquatic species and aquatic ecosystems (e.g., lakes, rivers, marshes, oceans). Solar UV radiation penetrates to ecological significant depths in aquatic systems and can affect both marine and freshwater systems from major biomass producers (phytoplankton) to consumers (e.g., zooplankton, fish, etc.) higher in the food web. Many factors influence the depth of penetration of radiation into natural waters including dissolved organic compounds whose concentration and chemical composition are likely to be influenced by future climate and UV radiation variability. There is also considerable evidence that aquatic species utilize many mechanisms for photoprotection against excessive radiation. Often, these protective mechanisms pose conflicting selection pressures on species making UV radiation an additional stressor on the organism. It is at the ecosystem level where assessments of anthropogenic climate change and UV-related effects are interrelated and where much recent research has been directed. Several studies suggest that the influence of UV-B at the ecosystem level may be more pronounced on community and trophic level structure, and hence on subsequent biogeochemical cycles, than on biomass levels per se.

“…86,87 DMS enters the atmosphere where it reduces the incoming solar radiation and forms cloud nuclei. 88,89 DMSP production and DMS release are correlated with sea ice melting. 90 The environmental advantage of DMSP-producing phytoplankton due to increased temperature could further complicate the feedback mechanisms involving cloud formation.…”

Productivity of aquatic primary producers under global climate change

The productivity of aquatic primary producers depends on a number of biotic and abiotic factors, such as pH, CO2 concentration, temperature, nutrient availability, solar UV and PAR irradiances, mixing frequency as well as herbivore pressure and the presence of viruses, among others. The effects of these factors, within a climate change context, may be additive, synergistic or antagonistic. Since some of them, e.g. solar radiation and temperature, vary along a latitudinal gradient, this perspective about the effects of global climate change on primary producers will consider ecosystems individually, separated into polar (Arctic and Antarctic), temperate and tropical waters. As coastal waters are characterized by lower light penetration and higher DOM and nutrient concentrations, they are considered in a separate section. Freshwater systems are also governed by different conditions and therefore also treated in their own section. Overall, we show that although there are general common trends of changes in variables associated with global change (e.g. the impact of UVR on photosynthesis tends to decrease with increasing temperature and nutrient input), the responses of aquatic primary producers have great variability in the different ecosystems across latitudes. This is mainly due to direct or indirect effects associated with physico-chemical changes that occur within water bodies. Therefore we stress the need for regional predictions on the responses of primary producers to climate change as it is not warranted to extrapolate from one system to another.

“…25 Nevertheless, in comparison to other regions, the Gulf of Guinea has received little or no attention as regarding the measurements, distribution and emission of biogenic sulphur in the seawater. 26,27,28 In view of this, the vapour generation -chemiluminescence (VG-CL) detection system was fabricated to be used for the determination of DMS and DMSP in the seawater. 28 The focus of this study was, therefore, to use the fabricated and re-modified VG-CL to determine the concentration of DMS and DMSP in the samples of the seawater collected from the tropical Atlantic Ocean around Lagos State (Elegushi and NIOMR).…”

The vapour generation -chemiluminescence (VG-CL) detection system that was designed for this research was used for the measurement of dimethylsulphide (DMS) and its precursor dimethylsulphoniopropionate (DMSP). The present study attempted the development of a highly sensitive, portable and cost-effective detection system based on vapour generation and chemiluminescence for a pilot assessment and determination of DMSP and DMS concentrations in the Gulf of Guinea. The Elegushi Beach and Nigerian Institute of Oceanography and Marine Research (NIOMR) which are parts of the Atlantic Ocean were chosen as designated locations for this study. The average concentrations of DMSP and DMS in the surface seawater at the two locations ranged from 12.4 ± 0.2 to 26.5 ± 0.5 nM, 2.1± 0.0 to 40.9 ± 1.6 nM and 9.7 ± 0.4 to 44.9 ± 0.2 nM, 0 to 35.6 ± 2.3 nM, respectively. This study serves as a baseline measurement of the concentrations of DMS and DMSP in the tropical Atlantic Ocean (Lagos).
