The palynological samples included in this report were collected as part of the Alaska Department of Natural Resources' (Alaska Division of Geological & Geophysical Surveys (DGGS) and Alaska Division of Oil & Gas (DOG)) Cook Inlet Basin Analysis program. The focus of this program is to evaluate the stratigraphic trap potential and reservoir quality of coal-bearing Cenozoic strata in upper Cook Inlet basin and the reservoir quality of Mesozoic strata throughout the basin. The samples included in this report were collected in the Tyonek, Kenai, and Seldovia Quadrangles from September 2006 through July 2010. All samples in this report were processed by Russ Harms in Medicine Toenail Alberta, Canada. Prepared slides of recovered palynomorphs were analyzed by Dr. Pierre Zippi (Biostratigraphy.com, LLC). Sample collectors include Paul Decker (DOG), Emily Finzel (Purdue University); Bob Gillis (DGGS), Trystan Herriott (DGGS), Dave LePain (DGGS), Dave Mauel (DGGS), Jacob Mongrain (UAF and DGGS), and Marwan Wartes (DGGS).
The purpose of this report is to present palynological data collected in the Tyonek, Kenai, and Seldovia quadrangles in the Cook Inlet region of Alaska.
The DGGS metadata standard extends the FGDC standard to include elements that are required to facilitate our internal data management. These elements, referred to as "layers," group and describe files that have intrinsic logical or topological relationships. Layers are named to correspond with the name(s) of the file(s). This dataset is described as a single layer titled:

This work was supported in part by the STATEMAP program under award numbers #G10AC00321 and #G09AC00177, administered by the U.S. Geological Survey. Additional funding was provided through a Capital Improvement grant from the State of Alaska
The latitude and longitude values in this report were collected with handheld GPS units which are accurate to approximately 4 meters. Formation names were interpreted on the basis of prior geologic mapping. To facilitate accurate analysis, care was taken to collect fresh, unweathered, fracture-free outcrop samples within the study area. Age determinations were made by Pierre Zippi of Biostratigraphy.com, LLC based on climatically driven floral changes and biostratigraphic events. Zippi's error is documented as "confidence level" in his age calls.
No topologic relationships are present in this data set.
This data set includes all samples submitted for palynology analysis from the study area between the 2006 and 2010 field seasons.
The horizontal position accuracy on point data is approximately 4 meters based on the error range in the handheld GPS units used to collect spatial information.

stratigraphic nomenclature
During the 2006-2010 field seasons geologists collected fresh, unweathered, fracture-free outcrop samples within the study area. They recorded each sample's location and, when possible, noted the stratigraphic unit and their degree of certainty in assigning the stratigraphic unit. Locations of the samples listed in the table were collected with a handheld GPS device and plotted on maps to verify accuracy.

Sample
The unique identifier for each sample collected and analyzed.
Alaska Division of Geological & Geophysical Surveys
Sample names are depicted as follows: 2-digit year, 2-or3-letter collector's initials, 2-3 digit station number, and a 1-letter sample identifier (i.e. 01AA01a). The ends of some station numbers also have a -#, representing meterage in a measured section (i.e. 01AA01-1.1a). There are also several samples that follow the convention: 2-letter 1-digit identifiers representing measured section name and number, followed by a number indicating meterage within the measured section (i.e. AA1-1.1).

Formation
Geologic formation of the sample as determined in the field by the sample collector. The geologic formations that were sampled are the Tyonek, Beluga, Sterling, West Foreland, and Hemlock formations. A question mark indicates uncertain unit assignments. Unit names divided by a slash indicate two possible formations."Quaternary" is sometimes queried where the collector was uncertain if a sample was from a certain formation or whether it was an undifferentiated rock of Quaternary age.

Proposed stratigraphic nomenclature for Kenai Group, Cook Inlet
Geologic unit assignments were based on the nomenclature presented in Calderwood, K.W., and Fackler, W.C., 1972, Proposed stratigraphic nomenclature for Kenai Group, Cook Inlet basin, Alaska: American Association of Petroleum Geologists Bulletin, v. 56, p. 739â754.

Confidence_Level
Level of confidence in geologic age determination
Dr. Pierre Zippi (Biostratigraphy.com, LLC)
Confidence is a semi-subjective level determined by several factors, e.g.: 1)overall palynofloral abundance, diversity and preservation, 2)abundance and diversity taxa that are restricted by age, 3)abundance and diversity of taxa indicative of warm or cold climate phases, 4) stratigraphic succession of climate phases and/or ages in a series of stratigraphically constrained samples. A typical low confidence sample would be an isolated single sample with no physical stratigraphic field relationships; and low palynofloral abundance and diversity without age diagnostic taxa and a weak inconclusive climate signature. A typical high confidence sample would come from a long series of samples in a measured section; it (and most of the neighboring samples) would have a high abundance, high diversity palynoflora with age restricted taxa and a strong climatic signature. Note that the vendor did not assign confidence levels for all samples.
