CCLME SST anomalies in the context of variability and change.
In 2015, the observed annual mean CCLME SSTa was 1.
We examined the forcing of CCLME SST anomalies using AR(1) models in which observed SSTa derive from damped persistence of pre-existing anomalies plus some forcing.
While a mechanistic evaluation of the GOA influence on the CCLME is beyond the scope of this paper, this finding is consistent with a tendency found in the historical record for warm GOA SSTa to evolve into an Arc pattern warming the following year (DM2016).
Prey data were divided between established stocks of Pacific Harbor Seals in the northern CCLME, and compared overall.
The results of the review yielded 48 papers, reports, or theses that were directly relevant to Harbor Seal foraging for their descriptions of spatial behavior, quantitative and qualitative dietary analysis, or examination of potential fisheries interactions within the northern CCLME.
This literature review examined Pacific Harbor Seal diet across the northern CCLME by stock and geographic boundary, and contained information synthesized from a literature search of peer-reviewed literature, reports, and theses containing dietary information by frequency of occurrence in Harbor Seal scats and stomach.
This comparative review has highlighted the broad spatial and seasonal diversity of Pacific Harbor Seal prey consumption across the northern CCLME over a time span of more than 80 y, including variable regional and seasonal consumption of salmonid species.
Despite the aforementioned seasonal variability of the marine environment in the CCLME, climate forcing at interdecadal (e.
Ocean conditions in the CCLME after the 1998 regime shift can be summarized as a return to cooler, less stratified, and more biologically productive conditions with enhanced southward flow of water and organisms (King, 2005).
A warming trend during the late 20th century has been detected in all global oceans and accounts for a 1 [degrees]C increase in average annual water temperature in the CCLME over the past 50 years (Palacios et al.
Of course, there have been exceptions: 1999, an anomalously cool year in the CCLME (Schwing and Moore, 2000), produced one of the strongest year classes since the late 1980's (Fleischer et al.
