Latitude:  78.915 
Longitude:  11.938 
Elevation:  90 
Datalogger:  Q330 
Broadband:  STS1VBB_w/E300 
Accelerometer:  FBA_EST_EpiSensor_Accelerometer 
Telemetry Status at the NEIC:  Last Data In Less Than 10 Minutes 
Vault Condition: Seismometer piers are isolated from the floor and extend through two feet of soil plus an additional two feet into the permafrost. Large iron bolts extend from the bottom of the pier into the permafrost for another five feet. The building is on stilts and the piers are exposed for several feet to the elements, and strong winds cause noisy conditions.

As part of the annual calibration process, the USGS runs a sequence that includes a random, a step, and several sine wave calibrations. The USGS analyzes the random binary calibration signal in order to estimate the instrument response. The figures below show the results from the analysis of the most recent processed calibration at the station.
We use an iterative threestep method to estimate instrument response parameters (poles, zeros, sensitivity and gain) and their associated errors using random calibration signals. First, we solve a coarse nonlinear inverse problem using a least squares grid search to yield a first approximation to the solution. This approach reduces the likelihood of poorly estimated parameters (a localminimum solution) caused by noise in the calibration records and enhances algorithm convergence. Second, we iteratively solve a nonlinear parameter estimation problem to obtain the least squares bestfit Laplace pole/zero/gain model. Third, by applying the central limit theorem we estimate the errors in this pole/zero model by solving the inverse problem at each frequency in a 2/3rdsoctave band centered at each bestfit pole/zero frequency. This procedure yields error estimates of the 99% confidence interval.
