“…That said, MODIS-derived chlorophyll a measurements can be problematic in coastal waters during times of high suspended sediment (Gitelson et al 2008), as would be expected in times of cyclone activity (Larcombe and Carter 2004;Wolanksi et al 2005). While augmented suspended sediment concentrations may lead to an overestimation of chlorophyll a values, the presence of suspended sediments in the water column reduces clarity and has negative consequences for reef organisms (Russ and McCook 1999;Birrell et al 2005, Devlin andSchaffelke 2009).…”

Abstract. The Great Barrier Reef, the world's largest coral reef ecosystem, is subject to many environmental stressors. This study utilizes remotely sensed Moderate Resolution Imaging Spectroradiometer (MODIS) chlorophyll a concentration data to explore statistically significant relationships between local-scale tropical cyclone disturbance and relative water quality 10 between 2004-2014. The study reveals that tropical cyclone activity reduces water quality at 8-and 16-day time lags.Relationships suggest that at early stages (during and just after cyclone activity) algal response is induced primarily through wind-driven sediment re-suspension. However, wind speed in isolation only increases minimum levels of chlorophyll a, rather than mean or extreme upper values. At greater time lags (16-day), it is suggested that nutrient runoff from rainfall (and perhaps storm surge) increase phytoplankton activity, leading to detrimental ecological effects. The analyses systematically 15 demonstrate the dominance of tropical cyclone size on mean and extreme values of chlorophyll a during and after tropical cyclone activity (at 0-, 8-, and 16-day time lags). Both the total area affected and the area from which nutrients can be extracted have more impact on chlorophyll a concentrations than either the duration or intensity of the cyclone. Findings indicate that efforts to reduce nutrient and sediment leaching into the reef lagoon from the Queensland coastal lands need to be continued and improved. This will be particularly important in the context of climate change, since tropical cyclone 20 frequency, dynamics and characteristics are likely to change.

“…As the tropical cyclone moves over the reef lagoon, the intense wind and wave energy can re-suspend benthic sediments (Marra et al 1990;Larcombe and Carter 2004;Wolanksi et 10 al. 2005) with an associated pulse of nutrients from lagoon and reef pore water (Furnas 1989).…”

“…Under the current climate regime, the distribution of precipitation is strongly seasonal and strongly controlled by the distribution and paths of tropical cyclones and the development of monsoon troughs. The prevailing southeasterly winds maintain a strong northwesterly current along the shoreface and inner shelf (Hopley 1982), which inhibits the dispersal of terrigenous sediment across the shelf (Larcombe & Woolfe 1999;Orpin et al 1999;Larcombe & Carter 2004). Episodes of intense rainfall during the summer months (rainy season) result in rapid runoff, triggering short-lived, high-magnitude flooding events (Alexander et al 1999).…”

Rivers have long been recognized for their ability to shape reef-bound volcanic islands. On the time-scale of glacial-interglacial sea-level cycles, fluvial incision of exposed barrier reef lagoons may compete with constructional coral growth to shape the coastal geomorphology of ocean islands. However, overprinting of Pleistocene landscapes by Holocene erosion or sedimentation has largely obscured the role lowstand river incision may have played in developing the deep lagoons typical of modern barrier reefs. Here we use high-resolution seismic imagery and core stratigraphy to examine how erosion and/or deposition by upland drainage networks has shaped coastal morphology on Tahaa, a barrier reef-bound island located along the Society Islands hotspot chain in French Polynesia. At Tahaa, we find that many channels, incised into the lagoon floor during Pleistocene sea-level lowstands, are located near the mouths of upstream terrestrial drainages. Steeper antecedent topography appears to have enhanced lowstand fluvial erosion along Tahaa's southwestern coast and maintained a deep pass. During highstands, upland drainages appear to contribute little sediment to refilling accommodation space in the lagoon. Rather, the flushing of fine carbonate sediment out of incised fluvial channels by storms and currents appears to have limited lagoonal infilling and further reinforced development of deep barrier reef lagoons during periods of highstand submersion.Published by Elsevier B.V.
