ACCURACY ASSESSMENT OF UNDERWATER PHOTOGRAMMETRIC THREE DIMENSIONAL MODELLING FOR CORAL REEFS
Photogrammetry Underwater 3D Modelling Accuracy Assessment Calibration Point Clouds Coral Reefs Coral Growth Moorea
2016/11/11
Recent advances in automation of photogrammetric 3D modelling software packages have stimulated interest in reconstructing highly accurate 3D object geometry in unconventional environments such as und...
Coral Reefs and Biodiversity:A Critical and Threatened Relationship
Coral Reefs Biodiversity Threatened Relationship
2015/8/13
The importance of coral reef ecosystems may be seen in their numerous ecological, aesthetic, economic, and cultural functions. Atoll and barrier reef islanders recognize that healthy reefs are essenti...
Intense Benthic Grazing on Phytoplankton in Coral Reefs Revealed Using the Control Volume Approach
Coral Reefs Revealed Control Volume Approach
2015/8/5
What is our international investment in oceanography, and how has it changed over the years? Two seemingly simple questions that have daunted our community repeatedly. The first of these two questions...
The Moorea Coral Reef Long Term Ecological Research program affords a unique opportunity to study the implications of ocean acidification (OA) for coral reefs, as ongoing ecological and physical monit...
Coral Tissue Thickness as a Bioindicator of Mine-Related Turbidity Stress on Coral Reefs at Lihir Island,Papua New Guinea
Coral Tissue Thickness Bioindicator Mine-Related Turbidity Stress Coral Reefs Lihir Island Papua New Guinea
2015/7/15
Work described here assessed the feasibility of using variations in tissue thickness in massive Porites corals as a bioindicator for mine-related sediment stress. We examined parameters influencing co...
UTILIZING UNDERWATER THREE-DIMENSIONAL MODELING TO ENHANCE ECOLOGICAL AND BIOLOGICAL STUDIES OF CORAL REEFS

2015/4/23
The structural complexity of coral reefs profoundly affects the biodiversity, productivity, and overall functionality of reef ecosystems. Conventional survey techniques utilize 2-dimensional metrics t...
IMAGE FUSION APPLIED TO SATELLITE IMAGERY FOR THE IMPROVED MAPPING AND MONITORING OF CORAL REEFS: A PROPOSAL
Image Fusion Coral Reef Hyperion WorldView Environmental Management Image Classification
2014/4/28
A coral reef ecosystem, one of the most complex marine environmental systems on the planet, is defined as biologically diverse and immense. It plays an important role in maintaining a vast biological ...
Ocean acidification hot spots: Spatiotemporal dynamics of the seawater CO2 system of eastern Pacific coral reefs
Ocean acidification hot spots Spatiotemporal dynamics the seawater CO2 system eastern Pacific coral reefs
2014/4/16
Seawater CO2system dynamics were assessed from eastern Pacific reef sites in Panama ′ over 5 consecutive years(2003–2008) and twice in the Gala ′ pagos Islands (2003 and 2009). The seawater CO2system ...
Coral Reefs and Ocean Acidification
Coral reef ecosystems ocean acidification calcium carbonate reef-forming organisms
2015/7/6
Coral reefs were one of the first ecosystems to be recognized as vulnerable to ocean acidification. To date, most scientific investigations into the effects of ocean acidification on coral reefs have ...
Decline of coral reefs during late Paleocene to early Eocene global warming
coral reefs late Paleocene early Eocene global warming
2009/10/22
Since the 1980s the frequency of warming events has intensified and simultaneously widespread coral bleaching, and enhanced coral mortality have been observed. Yet, it remains unpredictable how tropic...
Although sexual reproduction by green algae is well documented, field studies of gamete release are rare. During 17 months of nearly daily monitoring (461 days) I regularly observed early morning spa...
A DIVER-OPERATED SUBMERSIBLE DRILL FOR STUDYING THE GEOLOGICAL HISTORY OF CORAL REEFS
coral reef DIVER EQUIPMENT core sample
2009/5/6
In the early 1970s I developed a hydraulically powered portable submersible drill for collecting cores from coral-reef substrates ranging from the exposed reef flat to the deep fore reef. A marked imp...

Hydrodynamic forces on larvae affect their settlement on coral reefs in turbulent, wavedriven flow
Hydrodynamic forces affect their settlement
2014/4/17
This study investigates a key aspect of how ambient flow affects the recruitment of water-dispersed marine larvae
onto benthic substrata: the sweeping away of larvae that have landed on surfaces. Thr...
