Sea level rise (SLR) is among the most pressing challenges for urban coastal areas. While geocentric (eustatic) SLR receives widespread attention in politics and media, relative at coast, mainly caused by land subsidence, still comparatively under-researched despite much higher rates. This paper introduces a combined natural social science study to bring subsidence more forefront of hazard research. We use data from radar altimetry, GNSS controlled tide gauge stations, InSAR mapping...
Abstract We investigate the sea level rise in Indonesia during period 1993–2011 using satellite altimetry and tide gauge data. Satellite indicates a positive with mean of 4 mm/yr, which is higher than global averaged rise. At four tide-gauge stations difference trends from co-located greater 3 mm/yr. Land subsidence found Jakarta, Surabaya Benoa. Enggano Tanjung Lesung vertical rates correspond GPS-derived between 2007 2009, indicating land at first station. Keywords: Sea changeland...
Drawing on Jakarta, Metro Manila and Singapore as case studies, we explore the paradox of slow political action in addressing subsiding land, particularly along high-density urban coastlines with empirical insights from coastal geography, geodesy analysis, geology, planning. In framing land subsidence a classic ‘wicked’ policy problem, also hybrid geological anthropogenic phenomenon that is unevenly experienced across contexts, paper uses three-step analysis. First, satellite-derived InSAR...
Abstract. Long-term monitoring of water resources and climate parameters at the scale river basins requires networks continuously operated in-situ stations. Since 2009, GFZ CAIAG, in cooperation with National Hydrometeorological Services (NHMS) Central Asia, are establishing such a regional network Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan, lately Afghanistan to collect observations meteorological hydrological deliver them end-users for operational tasks scientific studies. The newly...
Abstract. Coastal tide gauges do not only play a central role in the study of climate-related sea level changes but also tsunami warning systems. Over past five years, ten GPS-controlled gauge systems have been installed by German Research Centre for Geosciences (GFZ) Indonesia to assist development Indonesian Tsunami Early Warning System (InaTEWS). These stations are mainly at coastline facing Indian Ocean. The deliver information about instantaneous level, vertical control through GPS, and...
Abstract. On Boxing Day 2004, a severe tsunami was generated by strong earthquake in Northern Sumatra causing large number of casualties. At this time, neither an offshore buoy network place to measure waves, nor system disseminate warnings local governmental entities. Since then, buoys have been developed Indonesia and Germany, complemented NOAA's Deep-ocean Assessment Reporting Tsunamis (DART) buoys, moored Java. The suite sensors for detection has advanced adding GPS technology water...
Abstract. The Spermonde Archipelago, off the coast of southwest Sulawesi, consists more than 100 small islands and hundreds shallow-water reef areas. Most are bordered by coral reefs that grew in past response to paleo relative sea-level changes. Remnants these preserved today form fossil microatolls. In this study, we report elevation, age, estimates derived from microatolls surveyed five Archipelago. We describe 24 new index points, compare our dataset with both previously published...
Abstract. The regional research network Water in Central Asia (CAWa) funded by the German Federal Foreign Office consists of 18 remotely operated multi-parameter stations (ROMPSs) Asia. These were installed Research Centre for Geosciences (GFZ) Potsdam, Germany, close cooperation with Central-Asian Institute Applied (CAIAG) Bishkek, Kyrgyzstan; national hydrometeorological services Tajikistan and Uzbekistan; Ulugh Beg Astronomical Tashkent, Kabul Polytechnic University, Afghanistan. primary...
Abstract The Laurentide ice sheet was the largest late Pleistocene mass and contributor to Holocene pre-industrial sea-level rise. While glaciological dates suggest final melting between 8 6 ka, inversion of data indicates deglaciation at ca. 7 ka. Here, we present new chronostratigraphic constraints on disappearance based relative observations from tectonically stable north coast Java, Indonesia. Age-elevation flat upper surfaces 13 fossil intertidal corals (i.e., microatolls) indicate that...
Consistent calibration and monitoring is a basic prerequisite for providing reliable time series of global regional sea-level variations from altimetry.
