The OPAL Water Survey needs citizen scientists in England to record what life they see in local ponds and to conduct simple tests for water clarity and pH. By contributing, you'll help scientists learn more about how polluted lakes and ponds in England actually are.

Hurricane Opal -Wind and Water Line Survey INTRODUCTION Michael Baker Jr., Inc., on behalf of the Federal Emergency Management Agency (FEMA) and Property Loss Research Bureau (PLRB), conducted a wind and water line survey of the Hurricane Opal landfall area near Navarre and Ft. Walton Beach in Santa Rosa County, Florida, and other area By taking part in the OPAL water survey, you'll help scientists learn more about how polluted our lakes and ponds actually are - something we know surprisingly little about. Good water quality is essential for the many animals and plants that live in and around our lakes, ponds and rivers. Unfortunately, water is easily affected by.

The Open Air Laboratories (OPAL) Water Survey, launched in May 2010, aimed to encourage interest and participation in water science by developing a 'low-barrier-to-entry' water quality survey. During 2010, over 3000 participant-selected lakes and ponds were surveyed making this the largest public participation lake and pond survey undertaken to. Water Survey: A printable OPALometer. THE OPALOMETER (Water Clarity Measurer) How it works and what it can tell you about a pond or lake: Water clarity is a measure of how far light penetrates into water. This depends on particles suspended in the water and dissolved substances. High water clarity means more light can reach a greater depth in a. Opal consists of silicon dioxide, like quartz, plus an indefinite amount of water. Indefinite means different samples of opal contain different amounts of water. One may be 20% water and another 10% water. Because opal does not have a crystal structure, it is classified as a mineraloid—a mineral-like substance without well-formed crystals OPAL Water Survey data to generate a more robust dataset. Results: The OPAL Water Survey results provide a regional and national assessment of water quality as well as a first national picture of water clarity (as suspended solids concentrations).

Hurricane Opal: Florida Panhandle Wind and Water Line Survey (9.7 MB PDF) Summary: The goal of this investigation and study was to determine the approximate high-water elevation of the storm surge and combined storm surge and wave run-up in the open coast and inland bay areas affected by Hurricane Opal. The places surveyed included areas near. Unfortunately, water is easily affected by pollution from agriculture and industry, waste we throw away, and even pollutants in the air. By taking part in the OPAL water survey, you'll help scientists learn more about how polluted our lakes and ponds actually are - something we know surprisingly little about The OPAL water survey launched in May 2010 and is coordinated by University College London (UCL). The survey asks people to go pond-dipping and identify the invertebrates living in their local pond or lake. Using this information they can then find out how polluted the water is, as some creatures are more tolerant of pollution than others Activity C: Freshwater Survey If you are using a pond or lake as your freshwater habitat, students could use the OPAL Water Survey to look at the health of the pond. Based upon a scoring system, the survey uses the invertebrates found in the pond to assess the water quality The Survey encouraged greater understanding of the aquatic environment through public participation in water quality and aquatic biodiversity assessment and used high quality research to link the community, voluntary and statutory sectors.

The word opal comes from the Latin word opalus, which means precious stone. Opal is a form of noncrystalline quartz which is created from circulating, silica-bearing waters. When the silica solidifies it creates the gemstone opal which contains approximately 6 to 10 percent water Recent data suggests that the world supply of precious opal may have changed. In 2012, Ethiopian opal production was estimated to be 14,000 kg (31,000 lb) by the United States Geological Survey.

  1. They found that opal-A is mostly associated with bedrock, whereas more crystalline-hydrated silica is mostly associated with aeolian sediment. The findings suggest that silica in aeolian sediment has experienced longer interaction with water and, thus, has greater potential to preserve biosignatures
  2. A plume of thermal water having high total dissolved solids (TDS) concentration emanates from the north end of the Opal Mound fault and Roosevelt Hot Springs. This plume broadly defines the area of thermal outflow in which TDS concentrations decrease to the west, north, and south as the plume disperses in the unconsolidated basin-fill aquifer.
