    A complex mix of natural processes exist in nearshore and offshore waters which influence coastal and marine ecosystem productivity. An understanding of the biogeochemical processes involved is a key element in interdis ciplinary studies of primary production, oceanic flux and storage of carbon dioxide. Water circulation in the East African region is influenced by coastal currents driven by monsoon winds. There are four oceanic currents influenc ing Kenya’s coastal waters; namely the East African Coastal Current, the Somali Current, the Southern Equatorial Current and the Equatorial Counter Current. The Kenyan fishing industry is slowly embracing offshore fishing grounds, and the North Kenya Bank is emerging as the next fishery frontier. This study aims to provide insight on the processes driving the productivity of Kenya’s territorial waters. The variable Si* (the difference between available silicate [Si(OH)4] and nitrate [NO3- ]) was employed as a proxy of upwelling. It was highly positively correlated to chlorophyll-a, indicating that upwelling is a major phenomenon driving productivity in Kenyan territorial waters. Particulate Organic Carbon (POC) and Dissolved Oxygen (DO) exhibited a lesser positive correlation with chloro phyll-a, implying that remineralization also has some influence in the productivity of the area.

    Shoreline Change in Tanzania and Kenya: Manual for Assessment and Design of Mitigation Strategie
    (WIOMSA, 2015-01) Shaghude, Yohanna W.; Mburu, J. W.; Arthurton, Russell; Dubi, Alfonse M.; Gachuiri, S.; Kangwe, J.; Magori, C.; Msuya, Flower E.; Nyandwi, Ntahondi; Ochiewo, J.; Ong'anda, H.; Sallema, R.; Sanga, I.; Shalli, Mwanahija. S.; Uku, J.
    The aim of the manual is to raise awareness of the complex causes of, and the issues and risks associated with, shoreline change at local and national scales in Tanzania and Kenya, but also within the context of the WIO region. A greater awareness and application of shoreline planning and management can benefit coastal stakeholders, livelihoods, as well as local and national economies. The manual promotes the management of risks associated with shoreline change within the context of ICAM, with an emphasis on protecting the natural capital of the region’s coastal areas.
