Microfacies of Carbonate Rocks: Analysis, Interpretation and Application $182.99 The book provides a synthesis of the methods used in microfacies analysis, the potential of microfacies in evaluating depositional environments and diagenetic history, and the application of microfacies data in the study of carbonate hydrocarbon reservoirs and the provenance of archaeological materials. The first part of the book (Microfacies Analysis) deals with field and laboratory methods; the description and significance of microfacies data; quantitative microfacies analysis; diagenetic processes and diagenetic products; common textural limestone classifications and specific classifications for reef limestones, non-marine carbonates, recrystallized limestones and mixed carbonate-siliciclastic rocks; biological controls of carbonate sedimentation; and fossils in thin section. The second part (Microfacies Interpretation) is focused on the methods of making of microfacies types; diagonsotic criteria of palaeoenvironmental conditons and processes; the importance of integrated facies analysis including mineralogical and geochemical data; the definition of depositional facies models, facies zones and standard microfacies types, and the recognition of depositional constraints influencing cyclic carbonates, reef limestones, cold-water carbonates, vent and seep carbonates and mixed carbonate-siliciclastic rocks. The last chapter deals with secular variations of facies features. The third part of the book (Practical Use of Microfacies) underlines the facies controls of reservoir and host rocks, the importance of microfacies and diagenesis for understanding technological properties of carbonate rocks and the destruction and conservation of carbonate objects, and discusses the potential of microfacies for archaeometrical studies. Nearly 230 instructive plates (30 in color)showing thin-section photographs with detailed explanations form a central part of the content.

Carbonate Sedimentology $88.63 Carbonate rocks (limestones and dolomites) constitute a major part of the geological column and contain not only 60% of the world's known hydrocarbons but also host extensive mineral deposits. This book represents the first major review of carbonate sedimentology since the mid 1970's. It is aimed at the advanced undergraduate - postgraduate level and will also be of major interest to geologists working in the oil industry. "Carbonate Sedimentology" is designed to take the reader from the basic aspects of limestone recognition and classification through to an appreciation of the most recent developments such as large scale facies modelling and isotope geochemistry. Novel aspects of the book include a detailed review of carbonate mineralogy, non-marine carbonate depositional environments and an in-depth look at carbonate deposition and diagenesis through geologic time. In addition, the reviews of individual depositional systems stress a process-based approach rather than one centered on simple comparative sedimentology. The unique quality of this book is that it contains integrated reviews of carbonate sedimentology and diagenesis, within one volume.

Reef Status Magnesium Carbonate $35.49 Directly measures magnesium and resolves carbonate and borate. Test for magnesium titration based procedure in increments of 12.5 mg/l. Tests for carbonate alkalinity, borate and total alkalinity in 0.1 mg/l. Each kit performs 75 determinations for each test.

String Topology and Cyclic Homology $37.36 The subject of this book is string topology, Hochschild and cyclic homology. The first part consists of an excellent exposition of various approaches to string topology and the Chas-Sullivan loop product. The second gives a complete and clear construction of an algebraic model for computing topological cyclic homology. The book provides many references for the reader wishing to learn more about the subject, to which it gives a perfect introduction. It is therefore suitable for both graduate students and established researchers. It is certainly the best source of much information that was until now available only to specialists and covers material from the elementary bases to the most recent developments.

Reef Carbonate - 16.9 oz. $6.09 Reef Carbonate is a concentrated (4,000 meq/L) optimized blend of carbonate and bicarbonate salts designed to restore and maintain alkalinity in the reef aquarium. Calcium and carbonates are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. Used as directed, Reef Carbonate will not deplete calcium, magnesium, or strontium which usually tend to precipitate with increasing alkalinity. Treats 100 gallons of water for 2-4 months.

Cyclic Redundancy Check $44.79 A cyclic redundancy check (CRe is a non-secure hash function designed to detect accidental changes to raw computer data, and is commonly used in digital networks and storage devices such as hard disk drives. A CRienabled device calculates a short, fixed-length binary sequence, known as the CRC code or just CRC, for each block of data and sends or stores them both together. When a block is read or received the device repeats the calculation; if the new CRC does not match the one calculated earlier, then the block contains a data error and the device may take corrective action such as rereading or requesting the block be sent again. CRCs are so called because the check (data verification) code is a redundancy (it adds zero information) and the algorithm is based on cyclic codes. The term CRC may refer to the check code or to the function that calculates it, which accepts data streams of any length as input but always outputs a fixed-length code.

Geology of Carbonate Reservoirs: The Identification, Description and Characterization of Hydrocarbon Reservoirs in Carbonate Rocks $82.11 * An accessible resource, covering the fundamentals of carbonate reservoir engineering * Includes discussions on how, where and why carbonate are formed, plus reviews of basic sedimentological and stratigraphic principles to explain carbonate platform characteristics and stratigraphic relationships * Offers a new, genetic classification of carbonate porosity that is especially useful in predicting spatial distribution of pore networks. * Includes a solution manual

Seachem Reef Carbonate 2 liter $16.19 Seachem Reef Carbonate Reef Carbonate™is a concentrated (4,000 meq/L) optimized blend of carbonate and bicarbonate salts designed to restore and maintain alkalinity in the reef aquarium. Calcium and carbonates are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. To prevent this you must provide carbonates (Reef Carbonate™) and calcium (Reef Advantage Calcium™ or Reef Complete(R)). Used as directed, Reef Carbonate™ will not deplete calcium, magnesium, or strontium which usually tend to precipitate with increasing alkalinity. Reef alkalinity should be maintained at 3-5 meq/L (8-14 dKH). Alkalinity should not be allowed to fall below 2 meq/L. Whereas competing products simply use sodium bicarbonate, Reef Carbonate™ is made with a blend of carbonate and bicarbonate salts. This blend of salts results in Reef Carbonate™ yielding a pK of roughly 9.0 in saltwater (higher than competing products). In a closed reef system, the multitude of organics produced by reef inhabitants tends to force pH downward, but the advantage of Reef Carbonate's™ higher pK is a stabilization of pH around 8.3-8.4. Competing products' formulations make them incapable of such a claim, so pH will always fall below desirable levels for a reef aquarium. Features: . Concentrated (4,000 meq/L) optimized blend of carbonate and bicarbonate salts . Helps restore and maintain alkalinity in the reef aquarium Item Specifications: Size: 2 liter 4 liter Directions: BEGINNER: Use 1 capful (5 mL) per 80 L (20 gallons) twice a week. Best if diluted into a cup of freshwater, then added. Check alkalinity every 2 weeks and adjust dose or frequency accordingly. ADVANCED: Check alkalinity, then follow dosing regimen above until alkalinity is adjusted to 4-5 meq/L. Each dose will raise alkalinity by about 0.25 meq/L. Size or frequency of dose can be adjusted, but do not exceed 1 meq/L per day. Thereafter, use as required to maintain alkalinity. EXPERT: After determining the alkalinity consumption rate, set up a continuous drip system. Use the following formula to determine how much to add to your top-off water: m=va (m=mL of product to add to top off water, v=volume of tank in gallons, a=amount to raise alkalinity in meq/L). For example, if you want to raise alkalinity by 1 meq/L in a 50 gallon tank, then you would add 50x1=50 mL into the top-off water. HINTS: Best to pour in gradually near strong water movement. Do not add to a sump or other area of slow water exchange.

KH Carbonate Hardness Test Kit for Freshwater and Saltwater $5.99 Carbonate Hardness is a big factor in the pH of your tank. Certain fish cannot handle hard water, while for others a certain level of dissolved minerals is necessary. Test your water for Carbonate hardness so you can insure your fish have the proper KH for their health and well-being. For fresh and saltwater.

Where the Debate on Global Warming Is and Isn't - By Anthony Ricigliano

News and Advice by Anthony Ricigliano: As the debate over global warming continues apace, it's important to divide the issues between what is generally agreed upon, where the debate is really focused, and where it isn't. Despite the nay saying about global warming, a nearly unanimous number of scientists agree that the Earth has gotten warmer since the decade of the 70's. Statistics clearly show generally warmer temperatures accompanied by evidence backing those statistics. There are always dissenters, and this case is no different, but the debate isn't here.

Where the debate lies, with justification, is in determining the cause of these rising temperatures. One camp insists that warming is a natural cycle which will eventually play itself out, while the opposing camp points the finger squarely at the greenhouse gases emitted by the burning of fossil fuel for its numerous uses. Below are the three primary data points that clearly show that warming is occurring, the fourth showing the possible cause of it all.

Global Surface Temperature - Since circa 1950, the Earth's surface temperature has risen by about 1 degree Fahrenheit with most of the increase coming in the twenty years.

Shrinking Arctic Sea Ice - The National Snow and Ice Data Center tracks the ebb and flow of the amount of Arctic sea ice with methods including satellite imaging. Their imaging technology shows that from the late 70's to September of 2007, arctic sea ice declined by 32%. While September 2007 marked the lowest amount of Arctic sea ice on record, the area has witnessed higher levels of sea ice since that time. These levels, however, are still far below the numbers recorded in the late 70's.
Rising sea levels

Ice melting from glaciers, sea ice from the North Pole, and massive ice shelves at the South Pole add up to rising sea levels. Sea levels have been rising over the long term but have risen at an accelerated pace since 1993. The evidence standing behind this fact is a measurement of the rate of change from 1870 to the present day. From 1870 to 1992, sea levels rose an average of 1.7mm. Since 1993, that rate has almost doubled to 3.3mm

Carbon Dioxide Levels

While the first three data points can be classified as effects, this data point can be considered a cause. Carbon dioxide (CO2) occurs naturally in our atmosphere from a variety of sources. It also occurs as a result of the burning of fossil fuels. What statistics show is that for 400,000 years CO2 levels in the atmosphere stayed in a cyclical range. In 1950, CO2 levels broke out of that range on the upside and have never looked back.  

Try as they might, scientists have been unable to link this jump in CO2 levels to either natural or manmade events. Waiting for verification could be costly but so would solutions based on the wrong premise. While the debate rages on, the clock continues to tick.
