Photographs by: David Pitkin and Shawn W. Stephensen, USFWS ii Monitoring Common Murre and Brandt’s Cormorant Colonies Ver. 1.0 NWRS Survey Protocol Signature Page 1 Version is a decimal number with the number left of decimal place indicating the number of times this protocol has been approved (e.g., first approved version is 1.0.; prior to first approval all versions are 0.x; after first approval, all minor changes are indicated as version 1. x until the second approval and signature, which establishes version 2.0, and so on). A protocol is subject to versioning so it can be a living, dynamic document revisable with advancements and new techniques in field methods, data analyses, data processing, and data management that would improve the cost effectiveness, sustainability, and quality of its data over time. 2 Signature by National I&M Coordinator signifies approval of a protocol used at multiple stations from two or more Regions. iii Monitoring Common Murre and Brandt’s Cormorant Colonies Ver. 1.0 Survey Protocol Summary This protocol framework (PF) provides a foundation and guidance for consistent development of site-specific survey protocols (SSPs) with detailed instructions for conducting breeding colony surveys of common murre (Uria aalge) and Brandt’s cormorant (Phalacrocorax penicillatus) at locations throughout the California Current System (CCS). Cooperating Partners throughout the CCS are encouraged to utilize the survey guidance in this PF, where feasible. The individual SSPs should, at minimum, address elements identified in this PF pertinent to the survey method, staff, equipment, and environmental conditions at respective survey locations. This PF is the first such tool developed as part of the Pacific Seabird Inventory and Monitoring Program (PSP), which is a U.S. Fish and Wildlife Service (USFWS) inter-Regional program established for the purpose of coordinating, integrating, and supporting the full life cycle of seabird surveys conducted throughout the Service’s Pacific jurisdiction. It is intended to be the first in a series of PFs that will eventually establish suggested standards and minimum requirements for surveys contributing to the CCS-wide breeding population status and trend assessment of seabird species with significant portions of their global breeding populations in the CCS. Common murre (COMU) and Brandt’s cormorant (BRAC) are included in one survey protocol framework because they are surface nesters with overlapping nesting seasons, broadly occur throughout the CCS, often co-occur in dense aggregations at colony sites, and are therefore efficiently surveyed simultaneously within the CCS primarily by aerial photography. Although aerial photographic surveys will be the preferred method of field data collection for both species, boat- and land-based surveys will be used to provide supplemental contextual data, or when aerial surveys are not practical. As a result, all three survey methods are described in this protocol framework. The content and structure of the protocols described herein follows standards set forth in the U.S. Fish and Wildlife Service’s How to Develop Survey Protocols: a Handbook (Version 1.0) (USFWS 2013). Each of the following eight elements of a protocol is addressed in a narrative: introduction, sampling design, field methods, data management, analysis, reporting, personnel requirements and training, operational requirements, and references. Additionally, a series of standard operating procedures provides greater detail on recommended survey methods and technical aspects of this protocol. A 3-tiered sampling frame is described in this PF to integrate the timing and locations of COMU and BRAC colony surveys such that statistically rigorous estimates of population status, distribution, and trends may be achieved at sub-regional and CCS-wide scales. The data management element of the PF describes a centralized, interactive web-based application to be developed and deployed where all quality assured colony survey data could be easily entered by partners, and accessible for analyses and interpretation. Partners will set the degree to which their data are available to other users. iv Monitoring Common Murre and Brandt’s Cormorant Colonies Ver. 1.0 Suggested citation: Bridgeland, W.T., N. Nur, S.W.

Belkin and Peter C. Cornillon Abstract. Oceanic fronts shape marine ecosystems; therefore front mapping and characterization is one of the most important aspects of physical oceanography. Here we report on the first effort to map and describe all major fronts in the World Ocean’s Large Marine Ecosystems (LMEs). Apart from a geographical review, these fronts are classified according to their origin and physical mechanisms that maintain them. This first-ever zero-order pattern of the LME fronts is based on a unique global frontal data base assembled at the University of Rhode Island. Thermal fronts were automatically derived from 12 years (1985-1996) of twice-daily satellite 9-km resolution global AVHRR SST fields with the Cayula-Cornillon front detection algorithm. These frontal maps serve as guidance in using hydrographic data to explore subsurface thermohaline fronts, whose surface thermal signatures have been mapped from space. Our most recent study of chlorophyll fronts in the Northwest Atlantic from high-resolution 1-km data (Belkin and O’Reilly, 2007) revealed a close spatial association between chlorophyll fronts and SST fronts, suggesting causative links between these two types of fronts.

  • Tube-Nosed Seabirds) Unique Characteristics
    PELAGIC SEABIRDS OF THE CALIFORNIA CURRENT SYSTEM & CORDELL BANK NATIONAL MARINE SANCTUARY Written by Carol A. Keiper August, 2008 Cordell Bank National Marine Sanctuary protects an area of 529 square miles in one of the most productive offshore regions in North America. The sanctuary is located approximately 43 nautical miles northwest of the Golden Gate Bridge, and San Francisco California. The prominent feature of the Sanctuary is a submerged granite bank 4.5 miles wide and 9.5 miles long, which lay submerged 115 feet below the ocean’s surface. This unique undersea topography, in combination with the nutrient-rich ocean conditions created by the physical process of upwelling, produces a lush feeding ground. for countless invertebrates, fishes (over 180 species), marine mammals (over 25 species), and seabirds (over 60 species). The undersea oasis of the Cordell Bank and surrounding waters teems with life and provides food for hundreds of thousands of seabirds that travel from the Farallon Islands and the Point Reyes peninsula or have migrated thousands of miles from Alaska, Hawaii, Australia, New Zealand, and South America. Cordell Bank is also known as the albatross capital of the Northern Hemisphere because numerous species visit these waters. The US National Marine Sanctuaries are administered and managed by the National Oceanic and Atmospheric Administration (NOAA) who work with the public and other partners to balance human use and enjoyment with long-term conservation. There are four major orders of seabirds: 1) Sphenisciformes – penguins 2) *Procellariformes – albatross, fulmars, shearwaters, petrels 3) Pelecaniformes – pelicans, boobies, cormorants, frigate birds 4) *Charadriiformes - Gulls, Terns, & Alcids *Orders presented in this seminar In general, seabirds have life histories characterized by low productivity, delayed maturity, and relatively high adult survival.

We also thank our editor, Lisa Renaud. About tHE mILKEn InstItutE The Milken Institute is an independent economic think tank whose mission is to improve the lives and economic conditions of diverse populations in the United States and around the world by helping business and public policy leaders identify and implement innovative ideas for creating broad-based prosperity. We put research to work with the goal of revitalizing regions and finding new ways to generate capital for people with original ideas. We focus on: human capital: the talent, knowledge, and experience of people, and their value to organizations, economies, and society; financial capital: innovations that allocate financial resources efficiently, especially to those who ordinarily would not have access to them, but who can best use them to build companies, create jobs, accelerate life-saving medical research, and solve long-standing social and economic problems; and social capital: the bonds of society that underlie economic advancement, including schools, health care, cultural institutions, and government services. By creating ways to spread the benefits of human, financial, and social capital to as many people as possible— by democratizing capital—we hope to contribute to prosperity and freedom in all corners of the globe.

  • Seasonal and Spatial Fluctuations of the Phytoplankton in Monterey Bay
    SEASONAL AND SPATIAL FLUCTUATIONS OF THE PHYTOPLANKTON IN MONTEREY BAY A Thesis Presented to the Graduate Faculty of California State University, Hayward In Partial Fulfillment of the Requirements for the Degree Master of Arts in Biological Science by Russ Waidelich January, 1976 ABSTRACT The seasonal and spatial fluctuations of phyto­ plankton in Monterey Bay were described for an 18-month period. Low winter levels were mainly due to instabi­ lity of the water column, while the spring bloom was brought a·bout by the commencement of upwelling and the subsequent stabilization of the water column, with resi­ dence time of water regulating chlorophyll concentra­ tions. The summer minimum shortly followed the cessa­ tion of upwelling, when it appeared that nitrates were limiting, although zooplankton was a major factor in re­ ducing the algal standing stock at this time. Adequate illumination and relaxation of grazing pressure rather than specificity of water type appeared to be the major factors regulating the occurrence of the fall bloom, indicating that the seasonal pattern of Monterey Bay conforms generally to that of the mid­ latitude marine ecosystems. An examination of the spatial distribution o.f phytoplankton revealed lower values over the canyon during upwelling months due to advection of water to the shelf areas, and lower values in the same area during non-upwelling months due to subsidence or downwelling and tur·bul enc e . ii ACENOWLEDGlVJENTS Many people were responsible for helping to make this thesis possible. I would first like to thank my major advisors, Dr. Mary Silver and Dr. John Martin, for their valuable advice and support.
