The seasonal variation of the temperature and salinity of the surface waters of the British Columbia coastMcLeod, Donald Cameron January 1951 (has links)
For a number of years daily observations of surface temperature and salinity have been taken at ooeanographic stations (mostly lighthouses) on the B. C. coast. The present thesis is the first attempt that has been made to systematically analyse this data. The annual variation in temperature was seen to follow the general climatological trend of the B. C. coast at each of the stations, although a wide range in the amplitudes of these periodic variations was noted. The factors influencing the amplitude of the annual temperature curves were considered and such effects as incoming radiation, the extent of turbulence, the degree of shelter and the phenomena of upwelling due to horizontal wind stress (West Coast of Vancouver Island) have been discussed for each of the stations. Correlations were made between available meteorological information and the sea temperature observations and an attempt has been made to determine temperature contours of the B. C. coastal waters during the summer when the surface temperature is least uniform. The salinity observations were treated in an analogous manner to temperature and found to exhibit characteristic periodic annual variations. The stations were classified by means of these variations and the influences of precipitation and fresh water runoff, evaporation and mixing were discussed and correlations with meteorological observations were again made. / Science, Faculty of / Physics and Astronomy, Department of / Graduate

A study of the seasonal variation in temperature and salinity along the Oregon - Northern California coastBourke, Robert H. 03 September 1971 (has links)
This study examines the seasonal variability in temperature and
salinity of the nearshore waters off Oregon and Northern California.
Specifically, temperature and salinity variations during summer and
winter were ana1yzed from data gathered at shore stations along the
coast and from hydrographic data collected within 25 nautical miles
of shore.
At each of five shore stations a modal cell technique was used
to establish the temperature-salinity characteristics of the "normal"
water type existing at each station during summer and winter. A
classification scheme was employed to determine what local processes
were influential in altering the "normal" T-S characteristics at each
station.
In summer mixing with Columbia River plume water was found to be the
major modifying process along the Northern Oregon coast. Off Central and
Southern Oregon local heating and mixing with water from the shelf/slope
region were found to be most influential. In winter dilution due to precipitation
and subsequent runoff is the major modifying factor along the
entire coast except off Northern Oregon where mixing with shelf/slope
waters is slightly more influential.
The temperature and salinity structure of the near surface waters
(< 200 meters) was examined for four latitudinal zones off the Oregon-
Northern California coast. Within each zone profiles were constructed
at 5, 15, and 25 nautical miles offshore.
Surface waters are warmer and more saline in summer than in winter.
Surface temperatures increase seaward in both seasons. Surface salinities
increase seaward only during winter; in summer the increase is shoreward.
Offshore gradients of temperature and salinity are one to two orders of
magnitude greater than longshore gradients.
A strong thermocline to 30 meters and a strong halocline to 75 meters
is present in summer. In winter the water is isothermal to 50 meters
while a strong halocline is present to 100 meters. Below these levels
temperatures and salinities continue to slowly decrease and increase,
respectively, until at 200 meters they become constant throughout the
study area. Variability with distance from shore is significant only
in summer and is constrained to the upper 150 meters of the water column. / Graduation date: 1972

The effects of rainfall on temperature and salinity in the surface layer of the equatorial PacificBahr, Frederick L. 19 July 1991 (has links)
Measurements of temperature and salinity in the upper 5 m of the ocean
along the equator showed cool fresh anomalies due to rain showers. The
measurements were made between 140 W and 110 W during April 1987, an
El Nino year. The eastern equatorial Pacific was characterized by weak winds
(3 m/s average), high rainfall (1.6 cm/day), and warm surface temperatures
(28.4 C). Measurements of temperature were made from a catamaran float
at 0.5 and 1 m depth and at 5 m depth from the ship. Salinity was measured
at a depth of 1 m from the float and 5 m from the ship. The float was towed
off of the port side of the ship outside of the bow wake. Near-surface low
temperature and low salinity anomalies due to cool rainfall were encountered.
These anomalies were on average cool and fresh by 0.02 C and 0.2 PSTJ
with maximum values of 0.5 C and 1.6 PSU. The horizontal extent of the
anomalies ranged from less than 10 to more than 100 km. Rainfall depths
estimated from salt conservation agreed roughly with shipboard rain-gauge
measurements. The characteristic lifetime of the anomalies, estimated from
the ratio of the average rain depth to average rain rate, was about 10 hrs.
Rainfall temperatures were computed from the T-S mixing curves for three
large, newly-formed anomalies. The average rainfall temperature was 21 C.
Ocean buoyancy fluxes estimated for intense rain showers were an order of
magnitude larger than the fluxes in the absence of rain. / Graduation date: 1992 / Best scan available for p.15-16, 35. Original is a black and white photocopy.
