The forward-rapidity data is acquired with a pair of electromagnetic calorimeters which were built as part of the thesis. All aspects of the calorimeters from design to data analysis are dis-cussed. The calorimeters are used to measure non-zero asymmetries at forward-rapidity. The measurements extend to higher pT than previously measured. The data for pT >3 GeV/c are consistent with a 1/pT falloff. A constant asymmetry at high pT is excluded at the two sigma level. At mid-rapidity, precision asymmetries for neutral pions and η mesons are measured. These asymmetries are consistent with zero, and are expected to place bounds on the gluon Sivers function. Lastly, an exploratory double transverse spin asymmetry, AT T , measurement is carried out using coincidences between the two forward calorimeters.
