Close to the Belize Barrier Reef a mile or so off the coast of Ambergris Caye.
The Belize Barrier Reef is a series of coral reefs straddling the coast of Belize, roughly 300 meters offshore in the north and 40 kilometers in the south within. The Belize Barrier Reef is a 300 kilometers long section of the 900 kilometers long Mesoamerican Barrier Reef System, which is continuous from Cancún on the northeast tip of the Yucatán Peninsula through the Riviera Maya up to Honduras, making it the second largest coral reef system in the world after the Great Barrier Reef in Australia.
One of many shots. We went on an overnight trip on a ship that stays out on the reef. We got to snorkel four times in less than two days. The most amazing thing I have ever done
Installation of new equipment on the Spectacle Reef Light in northern Lake Huron established telemetry so that the data being gathered at the Eddy Covariance Station there can be monitored and collected at GLERL. An eddy covariance station measures atmospheric fluxes that allow over-lake evaporation to be estimated. 8/27/13. Credit: NOAA.
As nice as some photos turn out, so ugly others can turn out. This photo really doesn't do justice to beauty of the reef.

It's best to photograph this interesting area late or early in the day, when the colours fully come out. Remember to go at low tide.
Long Reef is unique in the Sydney region, as this headland is primarily made of Bald Hill Claystone. Mostly, it's a soft reddish rock, formed in the early Triassic period. The maximum thickness of this rock type is 20 metres.
An interesting variety of sedimentary rocks may be viewed at Long Reef. There's much iron influence here, most evident in the haematite. Much of the rocks here are of the Narrabeen Group of Sedimentary Rocks. There's also volcanic elements, such as a dyke of Jurassic dolerite. It was two metres tall, but it's since been partially removed for industry.
An abandoned copper mine is at Long Reef. A tunnel was dug into the purple claystone to explore for copper. It was situated along the claystone, between the red-brown oxidised rocks and grey-green reduced siltstone.
There are masses of fossils in the grey coloured claystone, however, they are mostly strands of vegetation and are not particularly impressive.
The commonest of the fossils being a primitive plant, known as the horsetail, "Phyllotheca". It's in the form of a stem with a whorl of leaves. These plants grew like reeds, which indicates they were swamp dwellers.
Less often, fossils of a shrub-like forked leaf "seed fern" (Dicroidium) may be seen. One more interesting fossil is of a large amphibian. The animal would have been around a metre long. Named "Bulgosuchus gargantua."
The commonest rock types are shales, sandstone and claystones. The sandstones are described as "lithic" meaning they have plenty of other rock fragments within.
The sands of the nearby beaches are orange in colour. Black coloured influences in the sand may be seen along the nearby beaches. Prominent of these dark minerals is rutile. Others include ilmenite and monazite. Geologists suggest these are derived from ancient rocks from the Broken Hill region.
Ages ago, I first visited this area in a school excursion. The school teacher was impressive intellectually. However, he mis-read the tide listings. And we went at high tide. He also said that so many of the fossils have been removed that there's hardly any left. This latter remark is barely true, as the rock keeps crumbling away and more fossils are revealed.
An amazing reef plus sandbar just north of big Negros Island in the Philippines. Sagay City is the jump-off point to get to the reef.
Many thanks to the Northern Negros State College of Science and Technology for hosting me!
It was nearly dark when we found this guy. It was in a area of fresh water a fair way from the coastal flats that we have seen them before. Looks like that's where it was going to settle for the night.

Eastern Reef Egret. Egretta sacra.
The Eastern Reef Egret is also called the Eastern Reef Heron, and the dark form the Blue Heron or Blue Reef Heron.
