Does Puget Sound Have A Long-Term Memory?, John Mickett, Wendi Ruef, J. A. (Jan A.) Newton
Salish Sea Ecosystem Conference
More than a decade of high-resolution, full-water column data collected by profiling UW ORCA/NANOOS moorings in several Puget Sound Basins are used to investigate interannual variability of near-surface and deep water properties. Although there are no significant trends in temperature, salinity, density and dissolved oxygen spanning the last decade, measurements show steady and relatively strong trends in these variables over periods of 3 to 5 years in both South Sound near bottom waters and in south Hood Canal deep water. For example, the annual minimum density in south Hood Canal deep water increased four years in a row from 2006 …

Salish Sea Ecosystem Conference
Local, state, federal, tribal and private stakeholders have committed significant resources to restoring Puget Sound’s terrestrial-marine ecosystem. Though jurisdictional issues have promoted a fragmented approach to restoration planning, there is growing recognition that a more coordinated systems-based restoration approach is needed to achieve recovery goals. This presentation describes our collaborative effort to develop and apply an integrated environmental and human systems modeling framework for the Puget Sound Basin, inclusive of all marine and land areas (1,020 and 12,680 sq. mi.). Our goal is to establish a whole-basin systems modeling framework that dynamically simulates biophysical interactions and transfers (water, nutrients, contaminants, …

Recent And Projected Seasonal Changes To River Flows Combine With Human Pressures To Restructure The Base Of The Marine Food Web In Puget Sound, Christopher Krembs, Julia Bos, S. L. Albertson, Mya Keyzers, Allison Brownlee
Salish Sea Ecosystem Conference
Quantifying large-scale climate impacts, ecosystem responses, and human pressures requires sustained ecosystem monitoring and data integration. The Salish Sea is influenced by oceanic processes and hydrological cycles on land. The interplay of processes across the land-ocean continuum benefits the Puget Sound ecosystem by extending the productive cold-water food web of the upwelling system off Washington’s coast into Puget Sound during summer while buffering water temperatures in winter. Circulation patterns that drive water exchange between Puget Sound and the ocean are responding to climate and the timing of river flows. Historically the freshet and coastal upwelling coincide in summer and allow …

Salish Sea Ecosystem Conference
While ocean acidification was first investigated as a global phenomenon, coastal acidification has received significant attention in recent years, as its impacts have been felt by different socio-economic sectors (e.g., high mortality of shellfish larvae in aquaculture farms). As a region that connects land and ocean, the Salish Sea (consisting of Puget Sound and the Straits of Juan de Fuca and Georgia) receives inputs from many different sources (rivers, wastewater treatment plants, industrial waste treatment facilities, etc.), making these coastal waters vulnerable to acidification. Moreover, the lowering of pH in the Northeast Pacific Ocean also affects the Salish Sea, as …

How Did Large Scale Climate Anomalies Impact 2015 Phytoplankton Blooms In Puget Sound?, Juhi Lafuente, Christopher Krembs, S. L. Albertson, Allison Brownlee, Julia Bos, Laura Hermanson, Mya Keyzers
Salish Sea Ecosystem Conference
The Washington State Department of Ecology has been routinely monitoring marine water quality throughout the Puget Sound since 1973. An established historic baseline from 1999 to 2008 allows us to examine how water quality varies year to year as a result of both natural and human influences. The recent large scale climate anomaly, the Blob, impacted this region when a mass of warm water entered Puget Sound in fall 2014. In conjunction with higher than normal air temperatures, patterns of estuarine circulation and stratification were regionally altered in Puget Sound. Changes to these physical patterns affect ecosystem functions starting at …

Puget Sound Shoreline Inventory And Assessment Using Boat-Based Lidar, George M. Kaminsky, Alice Henderson, Heather Weiner, Hannah Drummond
Salish Sea Ecosystem Conference
Boat-based lidar of Puget Sound shorelines collected by the Washington State Department of Ecology are developed to provide a comprehensive inventory, classification, and analyses of site conditions and variability. For example, quantitative metrics of shoreline characteristics are derived from DEMs such as bluff crest height, bluff slope, bluff toe elevation, beach slope, and shoreline armoring elevations. These metrics can then be compiled and compared within and among drift cells to determine regional variability such as differences between updrift and downdrift beaches and the effect of fetch, orientation, and other exposure variables. Certain features can also be correlated to characterize how …
Using Ferry Monitoring Data To Explore The Importance Of Isotherms On The Winter Survival Of Northern Anchovy In Puget Sound, Suzan Pool, Christopher Krembs, Julia Bos, S. L. Albertson
Using Ferry Monitoring Data To Explore The Importance Of Isotherms On The Winter Survival Of Northern Anchovy In Puget Sound, Suzan Pool, Christopher Krembs, Julia Bos, S. L. Albertson
Salish Sea Ecosystem Conference
The Salish Sea displays strong seasonality in water temperature which can impose physiological limits on temperature sensitive species. Puget Sound, in winter, relies on ocean water as a heat source whereas in summer, the gradient is reversed. The dynamic exchange of Puget Sound with coastal water dictates the spatial and temporal patterns of isotherms that are relevant to temperature sensitive species. Recent winters with increased water temperature may expand the range of certain species to be able to survive in Puget Sound over the winter. Northern anchovy (Engraulis mordax) are pelagic spawners and survive in between 8 and 25 °C …

Extending Observations Further: Using Historic Biogeochemical Data To Understand Trends In Puget Sound, Ben Larson, Stephanie Jaeger, Wendy Eash-Loucks, Kimberle Stark, Bruce Nairn
Salish Sea Ecosystem Conference
Fluctuations in Puget Sound water quality reflect a combination of natural variability and anthropogenic influence. Predictions of how future changes will unfold requires an understanding of the complex interplay between these factors. Recent and ongoing measurement of water quality parameters allow a thorough assessment of variability over short time scales, but understanding changes over longer (e.g., decadal) timescales is critical for forecasting future changes. Examining long term trends requires the use of historical data, however, measurements that pre-date modern monitoring programs can be scarce, and the detection limits are often higher than newer analytical techniques. Here, we will consider several …

Challenges With Accurate Tracking Of Oil Spill Trajectories Within Puget Sound, Jonathan Whiting, Tarang Khangaonkar
Salish Sea Ecosystem Conference
Risk of oil spill within the Salish Sea has recently been highlighted by the construction of Canada’s Kinder Morgan Trans-Mountain Expansion Project, which is expected to increase oil tanker traffic through the Strait of Juan de Fuca by over 400 tankers per year. Complex circulation patterns in this high-energy fjord complicates the tracking of spills to aid both prevention and response. PNNL’s Salish Sea Model has been refined for over a decade and represents the leading hydrodynamic model for the region. In a recent project, the Salish Sea Model was paired with the National Oceanic and Atmospheric Administration’s General NOAA …

Regional Patterns In Seagrass Distribution, And Their Implications For Management In Greater Puget Sound, Bart Christiaen, Pete Dowty, Lisa Ferrier, Jeff Gaeckle, Helen Berry
Salish Sea Ecosystem Conference
Seagrasses provide important ecosystem services, and are sensitive to a wide range of environmental stressors, making them effective indicators of habitat condition. In Washington State, eelgrass (Zostera marina) is one of 25 Vital Signs for the health of Puget Sound. Management targets associated with this Vital Sign are defined on a soundwide scale. However, greater Puget Sound is a geomorphologically diverse system with complex circulation patterns and environmental gradients in tidal range, salinity, water clarity, and temperature. Given the variability in seagrass habitat, it is likely that depending on the location, different environmental drivers control the distribution of eelgrass and …
