Darwin Harbour is a typical macro-tidal, well mixed, and complex environment influenced by industries, human activities, and natural factors\u2014including winds, currents, river discharges, waves, and tides. As a case study, hydrodynamics and sediment dynamics in Darwin Harbour are investigated using moderate resolution imaging spectroradiometer (MODIS) measurements. This study focuses on understanding the variability of turbidity, mechanisms that control the variations of turbidity and analyzing field data to determine the main factors that influence the sediment dynamics in Darwin Harbour. The results of this study illustrate the seasonal turbidity variation is mainly influenced by the wind waves. The dredging campaigns in 2013 and 2014 wet seasons contributed to the rise of turbidity in Darwin Harbour. The action of tidal currents appears to be the dominant factor controlling the turbidity pattern in a spring\u2013neap cycle and the turbidity intra-tidal variation. In addition, the turbidity maximum zone (TMZ) near Charles Point is formed by the tidal current convergence based on the results of current modelling.<\/jats:p>","DOI":"10.3390\/rs10070997","type":"journal-article","created":{"date-parts":[[2018,6,22]],"date-time":"2018-06-22T10:56:28Z","timestamp":1529664988000},"page":"997","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Using 250-M Surface Reflectance MODIS Aqua\/Terra Product to Estimate Turbidity in a Macro-Tidal Harbour: Darwin Harbour, Australia"],"prefix":"10.3390","volume":"10","author":[{"given":"Gang","family":"Yang","sequence":"first","affiliation":[{"name":"The Sino-Australian Research Centre for Coastal Management, University of New South Wales, Canberra 2600, Australia"},{"name":"School of Physical, Environmental and Mathematical Sciences, University of New South Wales, Canberra 2600, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaohua","family":"Wang","sequence":"additional","affiliation":[{"name":"The Sino-Australian Research Centre for Coastal Management, University of New South Wales, Canberra 2600, Australia"},{"name":"School of Physical, Environmental and Mathematical Sciences, University of New South Wales, Canberra 2600, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth","family":"Ritchie","sequence":"additional","affiliation":[{"name":"The Sino-Australian Research Centre for Coastal Management, University of New South Wales, Canberra 2600, Australia"},{"name":"School of Physical, Environmental and Mathematical Sciences, University of New South Wales, Canberra 2600, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lulu","family":"Qiao","sequence":"additional","affiliation":[{"name":"College of Marine Geosciences, Ocean University of China, Qingdao 266100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guangxue","family":"Li","sequence":"additional","affiliation":[{"name":"College of Marine Geosciences, Ocean University of China, Qingdao 266100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhixin","family":"Cheng","sequence":"additional","affiliation":[{"name":"The Sino-Australian Research Centre for Coastal Management, University of New South Wales, Canberra 2600, Australia"},{"name":"School of Physical, Environmental and Mathematical Sciences, University of New South Wales, Canberra 2600, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,6,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2713","DOI":"10.3390\/rs2122713","article-title":"Using the Surface Reflectance MODIS Terra Product to Estimate Turbidity in Tampa Bay, Florida","volume":"2","author":"Rickman","year":"2010","journal-title":"Remote Sens."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"321","DOI":"10.1016\/j.ecss.2008.11.013","article-title":"Dynamics of the turbidity maximum zone in a macrotidal estuary (the Gironde, France): Observations from field and MODIS satellite data","volume":"81","author":"Doxaran","year":"2009","journal-title":"Estuar.
