Week 4:

• HW4 has been posted.
• Project 1, analysis of the Geology Data: project.doc    Data1.xls    due Monday May 2.
• I assume everyone know a bit about basic Chemistry.  The variables in the dataset are
  • Location
  • MO = month
  • PH = pH, pH scale -- ((chemistry) p(otential of) H(ydrogen); the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is acidic and less than 7 is basic))  See WordNet for the following.
  • K = potassium, K, atomic number 19 -- (a light soft silver-white metallic element of the alkali metal group; oxidizes rapidly in air and reacts violently with water; is abundant in nature in combined forms occurring in sea water and in carnallite and kainite and sylvite)
  • NA = sodium, Na, atomic number 11 -- (a silvery soft waxy metallic element of the alkali metal group; occurs abundantly in natural compounds (especially in salt water); burns with a yellow flame and reacts violently in water; occurs in sea water and in the mineral halite (rock salt))
  • CA = calcium, Ca, atomic number 20 -- (a white metallic element that burns with a brilliant light; the fifth most abundant element in the earth's crust; an important component of most plants and animals)
  • MG = magnesium, Mg, atomic number 12 -- (a light silver-white ductile bivalent metallic element; in pure form it burns with brilliant white flame; occurs naturally only in combination (as in magnesite and dolomite and carnallite and spinel and olivine))
  • CL = chlorine, Cl, atomic number 17 -- (a common nonmetallic element belonging to the halogens; best known as a heavy yellow irritating toxic gas; used to purify water and as a bleaching agent and disinfectant; occurs naturally only as a salt (as in sea water))
  • SI = silicon, Si, atomic number 14 -- (a tetravalent nonmetallic element; next to oxygen it is the most abundant element in the earth's crust; occurs in clay and feldspar and granite and quartz and sand; used as a semiconductor in transistors)
  • SO4 =
  • ALK = A pressure- and temperature-independent property of seawater that determines in part the carbon content of seawater. Carbonate alkalinity is the sum of the concen- tration of bicarbonate plus two times the concentration of the carbonate ions. Total alkalinity is the amount of acid required to bring seawater to a pH at which all dis- solved inorganic carbon becomes freely exchangeable. The alkalinity of the oceans is determined with potentiometric or normal titration techniques that detect and measure the presence of bicarbonate, carbonate, and borate ions.  See this Glossary online.
