F. TEMPERATURE Time Series: Offset Line Plots
Unfiltered temperature time series are shown for each of the COAST 2003
moorings. Temperatures for each mooring are shown at 11 days per page. The
temperature plots for each sensor are offset in the vertical, with the 11-day mean
positioned at the sensor depth. Temperatures above the 11-day mean correspond to
displacements above a horizontal line plotted at the sensor depth. The 11-day average
temperature for each sensor is shown in the right margin at the depth of the sensor. The
vertical bar on each page indicates the size of displacement equal to 1°C. The scale for
the Inner-shelf mooring is twice as large as for the Mid-shelf and Shelf-break moorings,
due to the smaller range of temperature fluctuations. Temperature data from the Midshelf and Met moorings were merged into one set of figures. The vertical range of
sensors from each of these mooring is indicated by a short blue horizontal line on the
depth axis.
Data are plotted for all depths for which temperature was recorded. Redundant
Vemco sensors were deployed at 4.5 m on the Inner-shelf and Shelf-break moorings; data
from sensors s/n 7309 (DIS) and s/n 7298 (DSB) are plotted here. Sample rates for the
temperature sensors ranged from 1 to 6 minutes (see Table 1).

G. SALINITY Time Series: Line Plots
Unfiltered salinity time series are shown for each of the COAST 2003 moorings.
Salinity was computed using unfiltered temperature and conductivity data. Salinities for
each mooring are shown at 11 days per page. Note that the salinity increases downward
on the vertical axis. Salinity data from the Mid-shelf and Met moorings were merged
into one set of panels. Sensor depths are indicated in the margins to the right of the
figures. Sample rate for the temperature and conductivity data was 1 minute for all
instruments (see Table 1).

H. SALINITY and SIGMA-THETA Time Series: Line Plots
Filtered salinity and potential density (sigma theta) time series are shown for each
of the COAST 2003 moorings. Salinity was computed using filtered temperature and
conductivity data; sigma theta was computed using filtered temperature and salinity.
Time series are shown at one page per mooring. Note that salinity and density increase
downward on the vertical axes. Time series from the Mid-shelf and Met moorings were
merged into one set of panels. Sensor depths are indicated in the margins to the right of
the figures.
The data represented in these figures are the outputs from a 40-hour lowpass
filter, interpolated to 1-hour intervals. Sample rate for the raw temperature and
conductivity data was 1 minute for all instruments (see Table 1). The filter employs a
Lanczos taper with a half width of 1840 minutes. There is no filter output at times for
which there is less than 50% data coverage in each side of the filter window. In addition,
there is no data output at times within one filter half-width of the start and stop times of
the time series.

I. METEOROLOGICAL Time Series Summary
Unfiltered short wave solar radiation, barometric pressure, wind speed, wind
vectors, and daily averaged air temperature from the COAST 2003 Met buoy are shown
on a single page. Solar radiation shown is the larger of two measurements at each time,
to account for sensor shading. Wind velocity vectors are shown in the oceanographic
convention of direction towards which the wind is blowing (up indicates blowing to the
north). Wind velocity is computed from 15-minute averages of 5-second sampled wind
speed, wind direction, and buoy compass. Solar radiation and barometric pressure are
15-minute averages of samples taken at 1-minute intervals. Daily averaged air
temperature shown is from Roger Samelson's Onset TidbiT temperature logger s/n
448599, which sampled at 7.5 minute intervals. Daily averages were computed for a
calendar day in Pacific Time. Heights of various instruments above the water are shown
in Table 1 d.

J. METEOROLOGICAL Time Series: Line Plots
Unfiltered short wave solar radiation, wind vectors, barometric pressure, wind
speed, and air temperature from the COAST 2003 Met buoy are shown at 11 days per
page together with air-sea temperature differences from all mooring sites. Both of the
redundant solar radiation measurements are shown for each time, illustrating sensor
shading. Wind velocity vectors are shown in the oceanographic convention of direction
towards which the wind is blowing (up indicates blowing to the north). Wind velocity is
computed from 15-minute averages of 5-second sampled wind speed, wind direction, and
buoy compass. Solar radiation and barometric pressure are 15-minute averages of
samples taken at 1-minute intervals. Air temperature measurements were made with
redundant Onset TidbiT temperature loggers deployed by Roger Samelson on the Met
(toroidal), Inner-shelf (spar) and Shelf-break (spar) buoys (Table 1). The TidbiT sensors
sampled temperature at 7.5 minute intervals. Air temperature shown is from temperature
logger s/n 448599 on the Met mooring. Air-sea temperature differences were formed
between TidbiT temperature loggers at 2.1 m above the water and SBE-37 microcats at
either 1.5 m or 2.4 m depth (see Table 1). The air-sea temperature difference was formed
using 1-minute interpolated air temperature data from loggers: s/n 448600 at the Innershelf mooring, s/n 448599 at the Met mooring, and s/n 448602 at the Shelf-break
mooring.

K. PRESSURE Time Series: Line Plots
Unfiltered time series of pressure fluctuations from sensors on each of the COAST 2003
subsurface moorings are shown on a single page. The record-average of pressure from each
sensor is shown in the margin to the right. Nominal depths of the sensors are shown in Table 1.
Pressure was sampled at 4-minute intervals by the MDRs and the 1 MHz Nortek AquaDopp at
19 m depth on the Mid-shelf mooring, and at 2-minute intervals by the SBE-39s and the Nortek 2
MHz AquaDopp at 87 m depth on the Mid-shelf mooring. The Nortek time series have lower
levels of high-frequency noise due to averaging of the pressure signal over the averaging interval
(see Table 2), whereas the MDRs and SBE-39s provide instantaneous measurements of pressure.
