Book Description
“The Atlantic Zone Monitoring Program (AZMP) was implemented in 1998 with the aim of (1) increasing Fisheries and Oceans Canada’s (DFO) capacity to understand, describe, and forecast the state of the marine ecosystem and (2) quantifying the changes in the ocean’s physical, chemical, and biological properties and the predator–prey relationships of marine resources. AZMP provides data to support the sound development of ocean activities. A critical element in the observational program of AZMP is an annual assessment of the distribution and variability of nutrients and the plankton they support. In this document, we review the chemical and biological oceanographic (lower trophic levels) conditions in the Gulf of St. Lawrence (GSL) in 2015. Overall, temperature conditions were somewhat warmer than normal, especially in August and September, following a delayed onset after cold winter conditions (above-normal surface mixed cold layer depth and above-normal sea-ice volume due to the coldest February since 1993. Deepwater temperatures have continued to increase as have the bottom areas covered by waters warmer than 6°C because of inward advection of warm water through Cabot Strait; both of these saw record-high values in 2015. This report describes the 2015 production cycles and community composition of phytoplankton and zooplankton in this context"--Introd., p. 1.

Book Description
Showing how big-picture patterns can help overcome the failures of conventional management, this book is ideal for students, researchers and professionals involved with marine fisheries. It explores not only the current practice of the 'ecosystem approach' to fisheries management but also its critical importance to even larger perspectives. The first section gives a valuable overview of how more and more of the complexity of real-world systems is being recognized and involved in the management of fisheries around the world. The second section then demonstrates how important aspects of real-world systems, involving population dynamics, evolution and behavior, remain to be taken into account completely. This section also shows how we must change the way we think about our involvement in, and the complexity of, marine ecosystems. The final chapters consider how, with the use of carefully chosen macroecological patterns, we can take important steps towards more holistic management of marine fisheries.

Book Description
This document is part of an initiative conducted by the Canadian Department of Fisheries and Oceans to report on the ecological "State of the Oceans" (SOTO). It concisely summarizes the most recent scientific information relevant to six key issues that have a considerable impact on the ecosystems of the Estuary and Gulf of St. Lawrence Large Ocean Management Area (LOMA): (1) hypoxia in the deep waters, (2) ocean acidification, (3) changes in seasonal sea-ice cover and its effect on marine mammals, (4) aquatic invasive species, (5) impacts of fishing and climate-driven changes in exploited marine populations and communities, and (6) potential impacts of grey seal predation on groundfish populations. The information is presented following the Drivers Pressures State Impacts and Responses approach (DPSIR) to the identification and management of the environmental effects. Existing reports on the structure, state, and management of the Estuary and Gulf of St. Lawrence LOMA are also reviewed with the aim to highlight the manner in which the present report complements that information. Furthermore, a brief discussion on what should constitute the structure and content of a more effective SOTO report is presented as an explanation for the nature of the present report and as a guide for future SOTO reporting in the LOMA. The report results from a collaboration between ocean scientists and managers in support of integrated management in the St. Lawrence LOMA.

Book Description
This assessment is a summary of the accumulated scientific understanding of the estuary and Gulf of St. Lawrence. It discusses the extent of anthropogenic modifications to this marine environment, points out principal uncertainties that hinder our understanding, and identifies important regional environmental issues. Many assessments attempt to provide easy-to-understand information to a wide, non-specialist audience. Others are directed more specifically to scientists, but include a conclusions section written for non-scientists. This document offers something of a middle approach: it is intended to be understood by a non-specialist audience, albeit one with a general knowledge of contemporary science. At the same time, it gives the professional scientist a broad-scale synthesis of current information.
