Ecosystem status report of the California current for 2019–20: a summary of ecosystem indicators compiled by the California current integrated ecosystem assessment team (CCIEA)


This document is an expansion of the ecosystem status report (ESR) provided by the California Current Integrated Ecosystem Assessment Team (CCIEA Team) to the Pacific Fishery Management Council (PFMC) in March 2020 (Harvey et al. 2020). The CCIEA Team provides ESRs annually to PFMC, as one component of the overall CCIEA goal of providing quantitative, integrative science tools, products, and synthesis in support of a more holistic (ecosystem-based) approach to managing marine resources in the California Current. The ESR features a suite of indicators codeveloped by the CCIEA Team and PFMC. The suite of indicators was initially identified in 2009, and has been refined and updated over the years to best capture the current state of the California Current ecosystem (CCE). The analyses in this document represent our best understanding of environmental, ecological, and socioeconomic conditions in this ecosystem roughly through late 2019 and early 2020. Because the time required to process data varies for different indicators, some of the resulting time series are slightly more up-to-date than others. The time series for some indicators (snowpack, sea lion reproduction and pup growth, seabirds, fishery landings, fishery revenue, and nonfishing human activities) have been updated since the March 2020 report to PFMC (Harvey et al. 2020).

Actes du Colloque: acidification des océans : conséquences sur les écosystèmes et les activités humaines (in French)

Qu’est-ce que l’acidification des océans ? Quelles en seront les conséquences potentielles sur les activités économiques ? Comment réagir ? Telles sont les questions qui ont été abordées lors de cette journée qui a rassemblé scientifiques, acteurs professionnels et associations.

Organisé par la FRB et le MTES en partenariat avec l’Ifremer, ce colloque s’appuie sur les expériences de terrain et sur les résultats des projets scientifiques financés par le ministère de l’écologie dans le cadre du programme de recherche “Acidification des océans”.

Emerging ocean acidification threatens Baltic Sea ecosystems

More jellyfish but fewer mussels – the expected spread of ocean acidification can have major effects on species composition in the Baltic Sea. It may also make the water slimier and less attractive for swimming. To protect unique ecosystems and future food production, carbon dioxide emissions must be dramatically reduced and measures must be taken against eutrophication, overfishing and releases of hazardous substances.

It is now well known that the world’s large-scale emissions of greenhouse gases are leading to climate change and global warming. However, there is less awareness of what has been called “the other carbon dioxide problem” – ocean acidification.

An annual update on the state of ocean acidification science in Alaska – 2019 update

What is Ocean Acidification?

Scientists estimate that the ocean is 30% more acidic today than it was 300 years ago, traceable to increasing levels of atmospheric carbon dioxide (CO2) from fossil fuel burning and land-use change, such as deforestation. As human-generated CO2 is released into the atmosphere, about a third is absorbed by the ocean. The additional CO2 lowers the pH of the seawater, driving the process known as ocean acidification (OA). The current pace of OA is faster than any time on record — 10 times faster than the last major acidification event 55 million years ago.

Why is Alaska at Risk?

Ocean acidification is expected to progress faster and more severely in Alaska than lower latitudes. Waters in Alaska are both ‘cold and old’: cooler water temperatures and global circulation patterns mean that Alaska waters naturally hold more CO2 year round. On top of this high baseline concentration of CO2, other processes also make Alaska’s waters more naturally acidic on a seasonal scale.

Monitoring ocean acidification in Norwegian seas in 2018

This is the annual report from 2018 based on the program: ‘Monitoring ocean acidification in Norwegian waters’ funded by the Norwegian Environment Agency. The measurements are performed by the Institute of Marine Research (IMR), Norwegian Institute for Water Research (NIVA), NORCE Norwegian Research Centre (NORCE) and the Univsersity of Bergen (UiB).

The measurements cover the area from North Sea/Skagerrak, the Norwegian Sea, and the seasonally ice covered Barents Sea. IMR conducted water column measurements along repeated transects, mainly in winter in the Skagerrak (Torungen–Hirtshals section), Norwegian Sea (Svinøy-NW, Gimsøy-NW sections), Barents Sea (Fugløya-Bjørnøya, NE Barents Sea section), and at Skrova and Arendal coastal stations. NORCE-UiB conducted water column measurements at Station M, continuous surface measurements at the same site, and water column measurements at three stations in the Hardanger region.

NIVA performed surface water measurements on two sections; Oslo-Kiel (North Sea/Skagerrak) and Tromsø-Longyearbyen (Barents Sea opening) during all of 2018. This report presents and discusses some time series for the period 2011-2018.

Opportunities for increasing ocean action in climate strategies

The global ocean is warming, acidifying and losing oxygen, and sea level is rising. As a result, keystone species and ecosystems such as warm-water coral reefs, seagrass meadows and kelp forests will face high to very high risks by the end of this century even under low carbon dioxide (CO2) emissions (IPCC, 2019). Moreover, low-lying coastal settlements will face moderate to high sea-level rise risks by the end of the century, even under full and timely implementation of the Paris Agreement, unless comprehensive and intense adaptation efforts are undertaken. This calls for a dramatic scaling up of efforts towards ambitious mitigation and adaptation.

The ocean offers opportunities to reduce the causes and consequences of climate change, globally and locally, as shown by The Ocean Solutions Initiative (Gattuso et al., 2018) and other recent reports (Hoegh-Guldberg et al., 2019; Because the Ocean 20192). However, countries have poorly used ocean-based measures for tackling climate change and its impacts, in their Nationally Determined Contributions (NDCs; Gallo et al. 2017) under the Paris Agreement. The process towards the 5-year revision of NDCs, culminating at the 26th Conference of the Parties of UNFCCC, offers an opportunity for countries to adopt more ocean-inclusive mitigation and adaptation strategies.

In this Policy Brief we assess 18 ocean-based measures to support climate policies and the revision of NDCs in the areas of mitigation and adaptation. Ocean-related measures should not be considered as a substitute for climate mitigation on land, which must also be strongly pursued for the benefit of the atmosphere as well as the ocean.
