  1. Shoreline change on nine reef islands over a seven-decade period

    Mann, Thomas; Westphal, Hildegard
    Atoll islands are subject to a variety of processes that influence their geomorphological development. Analysis of historical shoreline changes using remotely sensed images has become an efficient approach to both quantify past changes and estimate future island response. However, the detection of long-term changes in beach width is challenging mainly for two reasons: first, data availability is limited for many remote Pacific islands. Second, beach environments are highly dynamic and strongly influenced by seasonal or episodic shoreline oscillations. Consequently, remote-sensing studies on beach morphodynamics of atoll islands deal with dynamic features covered by a low sampling frequency. Here we present...

  11. Spatiotemporal monitoring of water quality in coral reefs of Tayrona National Natural Park, Colombian Caribbean, 2011-2013

    Bayraktarov, Elisa; Lazarus, Juan Felipe; Alarcón-Moscoso, Javier; Pizarro, Valeria; Carillo-Pacheco, L Vanessa; Eidens, Corvin; Wild, Christian
    Tayrona National Natural Park (TNNP; 11°17' - 11°22' N and 73°53' - 74°12' W) is a hotspot of coral reef biodiversity in the Colombian Caribbean, located between the city of Santa Marta (>455,000 inhabitants) and several smaller river mouths (Rio Piedras, Mendihuaca, Guachaca). The region experiences a strong seasonal variation in physical parameters (temperature, salinity, wind, and water currents) due to alternating dry seasons with coastal upwelling and rainy seasons. Here, a range of water quality parameters relevant for coral reef functioning is provided. Water quality was measured directly above local coral reefs (~10 m water depth) by a monthly...

  12. Isotopic composition of terrestrial plant waxes (dD and d13C of n-alkanes) of sediment core SO188_342 from the Northern Bay of Bengal for the last 18 ka

    Contreras-Rosales, Lorena Astrid; Jennerjahn, Tim C; Tharammal, Thejna; Meyer, Vera D; Lückge, Andreas; Paul, André; Schefuß, Enno
    The Indian Summer Monsoon (ISM) is a major global climatic phenomenon. Long-term precipitation proxy records of the ISM, however, are often fragmented and discontinuous, impeding an estimation of the magnitude of precipitation variability from the Last Glacial to the present. To improve our understanding of past ISM variability, we provide a continuous reconstructed record of precipitation and continental vegetation changes from the lower Ganges-Brahmaputra-Meghna catchment and the Indo-Burman ranges over the last 18,000 years (18 ka). The records derive from a marine sediment core from the northern Bay of Bengal (NBoB), and are complemented by numerical model results of spatial...

  14. High-resolution in situ seawater temperature in coral reefs of Tayrona National Natural Park, Colombian Caribbean, 2010-2013

    Bayraktarov, Elisa; Lazarus, Juan Felipe; Eidens, Corvin; Pizarro, Valeria; Wild, Christian
    The Tayrona National Natural Park (TNNP) is located at the northeastern Colombian coast between 11°17' - 11°22' N and 73°53' - 74°12' W. Despite of its relatively small coastline of only ca. 40 km, TNNP belongs to the most biodiverse areas of the tropical and subtropical Atlantic. Along its rocky coastline with capes, inlets and bays, the TNNP is home to a variety of seagrass beds, mangroves and coral communities. The TNNP region experiences strong seasonal variations through the alternation of rainy and dry seasons, and the occurrence of a wind-driven coastal upwelling which can lower the seawater temperature by...
