Data from: Century-scale changes in temperature, salinity, and dissolved oxygen in Puget Sound

These data accompany a paper submitted to Geophysical Research Letters.
The abstract is below. Over the last century, coastal oceans are losing
ecosystem-critical dissolved oxygen (DO). Changing coastal ocean
conditions influence water properties in connected estuaries, which are
also influenced by anthropogenic processes. We analyze nearly 100 years of
temperature, salinity, and DO data in Puget Sound - a temperate, fjordal,
urbanized estuary in Washington State, USA and the southernmost region of
the Salish Sea - during fall at the bottom of the water column. We observe
warming of about 1.4°C/century, consistent with regional trends and
similar to coastal ocean and local atmospheric warming. Salinity is
generally increasing, possibly due to shifting regional freshwater flow
timing. Finally, central Puget Sound is losing DO at a rate of 0.3-0.9
mg/L/century. Warming-driven changes in DO surface saturation account for
approximately 40-100% of this DO loss. Distal inlets in Puget Sound are
warming similarly, but variability exceeds the measured DO trends.
