Modelling South African cold-water coral habitats
Cold-water corals are found globally but little is known about energy flows associated with these habitats. The degree to which the benthic ecosystems containing cold-water corals are linked to the overlying pelagic ecosystems is also poorly understood. Observational studies have indicated that …

The Environmental Sensitivity of Cold-water Corals Lophelia pertusa
… sensitivity to oil and gas activities. Underwater videos from industry platform surveys were examined to identify L. pertusa, detail its occurrence at two sites (Heather and North Alwyn A (NAA)), and to look for evidence of exposure to drilling muds and cuttings (discharges). In addition, …

Numerical modeling of cold water injection into supercritical geothermal reservoirs
… study is to apply the improved supercritical air-water equation-of-state of the AUTOUGH2 numerical simulator to an artificial supercritical geothermal reservoir. A radially symmetric numerical model is used to investigate the response to cold water injection of a geothermal reservoir with …

The ecophysiology of the cold-water coral Lophelia pertusa (Scleractinia)
… most common and widespread framework-forming cold-water coral. It forms deep-water coral reefs and carbonate mounds supporting diverse animal communities on the continental shelf and on seamounts. Cold-water corals are found throughout most of the world’s oceans at depths of around 200 to 1000 …

Thermal Pollution Mitigation in Cold Water Stream Watersheds Using Bioretention
… the thermal impact associated with urban stormwater runoff in developing cold water stream watersheds. Temperature and flow data were collected during ten controlled trials at a bioretention facility located in Blacksburg, Virginia. It was determined that bioretention has the ability to reduce …

Short term recovery with cold water immersion following cycling in the heat
… completion of a bout of exercise in the heat, cold water immersion (CWI) is sometimes used by athletes to rapidly decrease their core temperature, and may facilitate recovery. Few studies however, have examined the effects of CWI after exercise in the heat on short term recovery. In addition, …

Peripheral blood flow changes in response to post-exercise cold water immersion
… considered to be the primary mechanism by which cold water immersion (CWI) enhances short-term (h) recovery and improves exercise capacity in the heat. However, improvement in exercise performance may be optimised at a given cooling magnitude. Water temperature and immersion duration influence …

Using biological traits analysis to investigate ecological functioning of cold-water coral reefs
Cold-water coral reefs are fragile, slow growing systems that are found in all oceans. Past research has focused on the species assemblages found on cold-water coral reefs. The species found on cold-water coral reefs are representative of the species assemblages found in the surrounding waters, …

Reproduction and Diet of Pseudemys Concinna Inhabiting a Cold Water Reservoir in Southwest Missouri
River cooters, Pseudemys concinna, were colleced using fyke nets from two locations, one hypothermic cove (Rockaway Slough) and one normothermic cove (Bull Creek) at Lake Taneycomo, from April 1993 to August 1994. Quantitative and qualitative analyses of adult diets from both sites showed great …

Reproduction and Diet of Kinosternon Odoratum Inhabiting a Cold Water Reservoir in Southwest Missouri
Kinosternon odoratum were collected from two habitats on Lake Taneycomo, a hypothermic cove (Rockaway Slough) and a normothermic cove (Bull Creek), from April 1993 through August 1994. Dietary analysis showed a significant difference between sites in the frequency of food items taken. There were no …

The Influence of Cold-Water Immersion on Limb Blood Flow and Thermoregulatory Responses to Exercise
… leading to suboptimal performance levels. Cold-water immersion (CWI) has become a widely used post-exercise recovery method to accelerate the recovery process by purportedly reducing the symptoms associated with exercise-induced muscle damage (EIMD). However, the underlying physiological …

EFFECT OF POST-EXERCISE COLD WATER IMMERSION ON MOLECULAR RESPONSES TO HIGH-INTENSITY INTERMITTENT EXERCISE
… to adapt to the prescribed training stimulus. Cold water immersion (CWI) is now widely used by athletes to enhance the rate of recovery following training and competition. However, little information currently exists with respect to its influence on skeletal muscle adaptation. Therefore, the …

The application of machine learning and 3D photogrammetry for cold-water coral habitat classification in the NE Atlantic
Cold-water coral reefs are complex structural habitats that represent one of the most important deep marine ecosystems. As three-dimensional habitats with high structural complexity, they provide ecosystem services that influence species abundance and biodiversity, being indicators of ecosystem …

Investigation of solid polymeric hollow fiber heat exchange devices for use in thermally-driven desalination processes
… heat exchange between hot brine (4 wt% NaCl) and cold water as well as between condensing steam and cold water without direct fluid-fluid contact using modules made out of solid polymeric hollow fibers of polypropylene (PP) and polyetheretherketone (PEEK) has been studied. The solid hollow fiber …

Investigating patterns in stream temperature and restorable alluvial water storage for climate resilience of freshwater habitat for salmon and trout
… the availability of habitat for aquatic species, watershed management must focus on the conservation and restoration of cold-water habitats for species such as salmon and trout that require cold water. Management actions that focus on restoring hydrologic processes can be used to adapt to climate …

Impacts of Reservoir Operations with Extreme Hydrologic and Climatic Conditions on Fish Sustainability below Shasta Lake
… River are required by law to provide artificial cold water habitat downstream for endangered winter-run Chinook salmon. At Shasta Lake, a temperature control device was installed on Shasta Dam that allows selective withdrawal of reservoir water at different elevations. There is debate, however, …

Impact of Flow Rate and Water Age on Opportunistic Pathogen Growth: Implications for Water Conservation, Fixture Design, and Policy
Water conservation efforts have led to a decrease of flow rates in buildings, increasing water retention time (WRT) and sometimes opportunistic pathogens (OPs) growth. A novel experiment with replicated distal pipes operated at commonly used flow rates was designed to evaluate the effects of water …
