    Description: Future ocean acidification (OA) will affect physiological traits of marine species, with calcifying species being particularly vulnerable. As OA entails high energy demands, particularly during the rapid juvenile growth phase, food supply may play a key role in the response of marine organisms to OA. We experimentally evaluated the role of food supply in modulating physiological responses and biomineralization processes in juveniles of the Chilean scallop, Argopecten purpuratus, that were exposed to control (pH 8.0) and low pH (pH 7.6) conditions using three food supply treatments (high, intermediate, and low). We found that pH and food levels had additive effects on the physiological response of the juvenile scallops. Metabolic rates, shell growth, net calcification, and ingestion rates increased significantly at low pH conditions, independent of food. These physiological responses increased significantly in organisms exposed to intermediate and high levels of food supply. Hence, food supply seems to play a major role modulating organismal response by providing the energetic means to bolster the physiological response of OA stress. On the contrary, the relative expression of chitin synthase, a functional molecule for biomineralization, increased significantly in scallops exposed to low food supply and low pH, which resulted in a thicker periostracum enriched with chitin polysaccharides. Under reduced food and low pH conditions, the adaptive organismal response was to trade-off growth for the expression of biomineralization molecules and altering of the organic composition of shell periostracum, suggesting that the future performance of these calcifiers will depend on the trajectories of both OA and food supply. Thus, incorporating a suite of traits and multiple stressors in future studies of the adaptive organismal response may provide key insights on OA impacts on marine calcifiers.

    Description: The second objective of the GROFLO project is to elucidate differences in nearshore community structures and ecosystem functions in relation to groundwater outflow. In February 1998 the second seagrass survey was carried out on Zanzibar. The aim of the survey was the same as in the first survey, in March 1997 in Kenya: to relate the rate of coastal groundwater outwelling to abundance, species diversity, productivity and population dynamics of lagoonal seagrasses. In this report results of both surveys on abundance and species diversity will be compared. Productivity and population dynamic samples are being analysed and those results will be presented in the next report.

    Description: The second objective of the GROFLO project is to elucidate differences in nearshore community structures and ecosystem functions in relation to groundwater outflow. In March 1997 and February 1998 two seagrass surveys were carried out. In the framework of the GROFLO project, models of groundwater outflow along the coasts of Kenya and Zanzibar Island were constructed (see contribution of VUB in this report). This made it possible to select study sites with contrasting groundwater-outflow rates. The aim of our surveys was to relate the rate of coastal groundwater outwelling to productivity and vitality of lagoonal seagrasses. The objective of the present study is to relate the rate of coastal groundwater outwelling to the abundance and species diversity of lagoonal seagrasses in East Africa. For the dominant species Thalassodendron ciliatum, supplemental data on nitrogen content and natural abundance of nitrogen isotopes in leaves were also collected. In addition, leaf-production rates, shoot demography, and flowering frequency of T. ciliatum were determined.

    Description: The OceanObs conferences are held once every 10 years for the scientific, technical, and operational communities involved in the planning, implementation, and use of ocean observing systems. They serve to communicate progress, promote plans, and to define advances in ocean observing in response to societies' needs. Each conference provides a forum for the community to review the state of the ocean observing science and operations, and to define goals and plans to achieve over the next decade.
    Description: The organizers of the OceanObs'19 conference thank the authors that conceived and jointly crafted the Community White Papers for their tremendous efforts, extensive international collaborations, and community wisdom. The organizers also thank the hundreds of reviewers of the CWPs for their dedication, and the time invested in reviewing the papers. The organizers of the OceanObs'19 conference wish to thank the chief editor of the journal, Dr. Carlos Duarte, and the Frontiers Marine Science staff, for their professionalism and support in this process.
