Abstract Submerged aquatic vegetation (SAV; e.g. seagrasses, macroalgae), forms key habitats in shallow coastal systems that provide a plethora of ecosystem services, including coastal protection, climate mitigation and supporting fisheries production. Light limitation is a critical factor influencing the growth and survival of SAV, thus it is important to understand how much light SAV needs, and receives, to effectively assess the risk that light limitation poses. Light monitoring is commonly… Expand

Parameterization of an optical model to refine seagrass habitat requirements in an urbanized coastline
Abstract Accurate simulation of the underwater light climate is a requirement to understanding and predicting the ecological benefits from initiatives to manage land-derived inputs of nutrients andExpand
A novel approach to model exposure of coastal-marine ecosystems to riverine flood plumes based on remote sensing techniques.
TLDR
This study developed a novel, complementary, approach to model exposure of coastal-marine ecosystems to land-based pollutants and used supervised classification of MODIS-Aqua true-color satellite imagery to map the extent of plumes and to qualitatively assess the dispersal of pollutants in plumes in the Great Barrier Reef.

A biophysical representation of seagrass growth for application in a complex shallow-water biogeochemical model
Seagrasses are a critical component of the healthy functioning of many coastal marine ecosystems. Capturing the dynamics of seagrass communities requires both a detailed representation of processesExpand

Model for deriving benthic irradiance in the Great Barrier Reef from MODIS satellite imagery.
TLDR
The bPAR model will provide baseline datasets to assess changes in bPAR and its external drivers and may form the basis for a future GBR water-quality index and may also be applicable to other coastal waters for which spectral IOP and high-resolution bathymetry data exist. Expand
Light thresholds derived from seagrass loss in the coastal zone of the northern Great Barrier Reef, Australia
There is a world-wide trend for deteriorating water quality and light levels in the coastal zone, and this has been linked to declines in seagrass abundance. Localized management of seagrass meadowExpand
A Global Crisis for Seagrass Ecosystems
ABSTRACT Seagrasses, marine flowering plants, have a long evolutionary history but are now challenged with rapid environmental changes as a result of coastal human population pressures. SeagrassesExpand
Light requirements of seagrasses determined from historical records of light attenuation along the Gulf coast of peninsular Florida.
TLDR
Light requirements were determined for four common and abundant seagrasses along the Gulf coast of peninsular Florida using a threshold detecting algorithm, confirming the need to address links between increased anthropogenic nutrient loads, eutrophication, reduced light penetration, and loss of seaglassed services.

Physical and biogeochemical controls on light attenuation in a eutrophic, back-barrier estuary
Light attenuation is a critical parameter governing the ecological function of shallow estuaries. In these systems primary production is often dominated by benthic macroal- gae and seagrass; thusExpand
