Lake Barco
Lake Barco is a lake in Putnam County, Florida, United States. It is within the Ordway-Swisher Biological Station of the Institute of Food and Agricultural Sciences. It is roughly circular, about in diameter. The nearest settlement is Melrose, Florida, about to the northwest. Characteristics Lake Barco is a sinkhole lake, typical of the region, where unconsolidated deposits on the surface have slumped into the highly soluble limestone of the upper Floridan aquifer. The organic-rich sediments of the lake bottom lie on an unconfined aquifer made up mostly of sands. Below this are the unconsolidated clays and sands of the Hawthorn Group, through which water can penetrate, and below this the Ocala Limestone of the upper Floridan aquifer. Groundwater monitoring wells have been placed around Lake Barco and nearby Lake Suggs to study the hydrology of the area. The lake has a mean annual temperature of and median rainfall of . It is recharged throughout the year. The lake is fed fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Putnam County, Florida
Putnam County is a county located in the northern part of the state of Florida. As of the 2020 census, the population was 73,321. Its county seat is Palatka. Putnam County comprises the Palatka, FL Micropolitan Statistical Area, which is included in the Jacksonville- St. Marys-Palatka, FL- GA Combined Statistical Area. The county is centrally located between Jacksonville, Gainesville, St. Augustine, and Daytona Beach. History Putnam County was created in 1849. It was Florida's 28th county created from parts of St. Johns, Alachua, Orange, Duval, and Marion counties. The county was named for Benjamin A. Putnam, who was an officer in the First Seminole War, a lawyer, Florida legislator, and the first president of the Florida Historical Society. The Putnam County Historical Society has determined that Benjamin A. Putnam is the grandson of Israel Putnam, for whom other counties and places in the United States are named. Benjamin A. Putnam died in the county seat of Palat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrology
Hydrology () is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and environmental watershed sustainability. A practitioner of hydrology is called a hydrologist. Hydrologists are scientists studying earth or environmental science, civil or environmental engineering, and physical geography. Using various analytical methods and scientific techniques, they collect and analyze data to help solve water related problems such as environmental preservation, natural disasters, and water management. Hydrology subdivides into surface water hydrology, groundwater hydrology (hydrogeology), and marine hydrology. Domains of hydrology include hydrometeorology, surface hydrology, hydrogeology, drainage-basin management, and water quality, where water plays the central role. Oceanography and meteorology are not included because water is only one of many important aspects within those fields. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zooplankton
Zooplankton are the animal component of the planktonic community ("zoo" comes from the Greek word for ''animal''). Plankton are aquatic organisms that are unable to swim effectively against currents, and consequently drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton, which are the plant component of the plankton community ("phyto" comes from the Greek word for ''plant''). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding). This means zooplankton cannot manufacture their own food but must eat other plants or animals instead — in particular they eat phytoplankton. Zooplankton are generally larger than phytoplankton, most are microscopic, but some (such as jellyfish) are macroscopic and can be seen with the naked eye. Many protozoans (single-celled protists that prey on other microscopic life) are zooplankton, including zooflagellates, fo ...

Macroinvertebrates
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', which ...

Gopher Frog
The gopher frog (''Lithobates capito'') is a species of frog in the family Ranidae, endemic to the south-eastern United States. It primarily inhabits the threatened sandhill communities, flatwoods, and scrub in the Atlantic coastal plain, where it is usually found near ponds. Subspecies Its two subspecies include the Carolina gopher frog (''L. c. capito''), and Florida gopher frog (''L. c. aesopus''). The dusky gopher frog ''(L. sevosus)'' had previously been considered a subspecies, but was elevated to species status in 2001. Conservation status Its primary threats include loss of habitat and fire suppression. It is entirely dependent upon small vernal pools for its annual reproduction.Richter, S. C., Young, J. E., Johnson, G. N., and Seigel, R. A. (2003). Stochastic variation in reproductive success of a rare frog, Rana sevosa: implications for conservation and for monitoring amphibian populations.

Sulfate
The sulfate or sulphate ion is a polyatomic anion with the empirical formula . Salts, acid derivatives, and peroxides of sulfate are widely used in industry. Sulfates occur widely in everyday life. Sulfates are salts of sulfuric acid and many are prepared from that acid. Spelling "Sulfate" is the spelling recommended by IUPAC, but "sulphate" was traditionally used in British English. Structure The sulfate anion consists of a central sulfur atom surrounded by four equivalent oxygen atoms in a tetrahedral arrangement. The symmetry is the same as that of methane. The sulfur atom is in the +6 oxidation state while the four oxygen atoms are each in the −2 state. The sulfate ion carries an overall charge of −2 and it is the conjugate base of the bisulfate (or hydrogensulfate) ion, , which is in turn the conjugate base of , sulfuric acid. Organic sulfate esters, such as dimethyl sulfate, are covalent compounds and esters of sulfuric acid. The tetrahedral molecular geometry of th ...

Deuterium
Deuterium (or hydrogen-2, symbol or deuterium, also known as heavy hydrogen) is one of two Stable isotope ratio, stable isotopes of hydrogen (the other being Hydrogen atom, protium, or hydrogen-1). The atomic nucleus, nucleus of a deuterium atom, called a deuteron, contains one proton and one neutron, whereas the far more common protium has no neutrons in the nucleus. Deuterium has a natural abundance in Earth's oceans of about one atom of deuterium among all atoms of hydrogen (see heavy water). Thus deuterium accounts for approximately 0.0156% by number (0.0312% by mass) of all the naturally occurring hydrogen in the oceans, while protium accounts for more than 99.98%. The abundance of deuterium changes slightly from one kind of natural water to another (see Vienna Standard Mean Ocean Water). (Tritium is yet another hydrogen isotope, with two neutrons, that is far more rare and is radioactive.) The name ''deuterium'' is derived from the Greek , meaning "second", to denot ...

Hawthorn Group
The Hawthorn Group is a stratigraphic unit that includes several geologic formations of Late Oligocene to Pliocene age in North Florida, United States. It is known for its phosphate rock resources, and for its rich assemblages of Neogene vertebrate fossils. It was originally called the Waldo Formation by L.C. Johnson of the United States Geological Survey in 1887, and later became the Hawthorne Group named for Hawthorne, Florida, where its phosphate-rich rock was quarried and processed for use as fertilizer. Age Period: Neogene Epoch: Miocene Faunal stage: Chattian through early Blancan ~28.4 to ~2.588 mya, a period of Location The Hawthorn Group extends from Suwannee County in the north and southward to Hernando County. It encompasses in part the counties of Gilchrist, Levy, Dixie, Citrus, Sumter, Alachua and Marion County.
