Temporal Inflection Points in Decorated Pottery: a Bayesian Refinement of the Late Formative Chronology in the Southern Lake Titicaca Basin, Bolivia

Christine Hastorf, Erik Marsh, Andrew Roddick, Maria Bruno, Scott Smith & John Janusek
The Late Formative Period immediately precedes the emergence of Tiwanaku, one of the earliest South American states, yet is one of the most poorly understood periods in the southern Lake Titicaca Basin (Bolivia). In this paper, we refine this period’s ceramic chronology with large sets of dates from eight sites, focusing on temporal inflection points in decorated ceramic styles. These points, estimated here by Bayesian models, index specific moments of change: (1) cal AD 140...

Simultaneous extracellular recordings of avian auditory neurons in zebra finches presented with all the repertoire of vocalizations used by this species for vocal communication

Julie Elie & Frederic Theunissen
This data set contains extra-cellular electrophysiological recordings from 6 urethane anesthetized adult zebra finches (Taeniopygia guttata), 4 males and 2 females. At each electrophysiological recording site a set of sounds was presented to the subject. This set was made from 10 ripple noise stimuli of 2 sec., and 20 songs of zebra finches and the vocalizations from the repertoire of 10 individuals. The maximum number of stimuli that could be selected in that procedure was...

Salinity and Velocity in Lower South San Francisco Bay

Olivia Hoang
In order to measure salinity gradients in the longitudinal, lateral, and vertical directions, a mesh of nine Ruskin RBR XR-420 CTDs and two Seabird SBE-37's were placed in various positions in all three dimensions. Lines 1, 2, 3, and 4 were placed in the channel. Lines 5 and 6 were placed in the shallows, lateral to line 2. Line 1 has two CTD's attached at the top and bottom of the water column. Lines 2...
