Abstract Sustained observations of marine biodiversity and ecosystems focused on specific conservation management problems are needed around the world to effectively mitigate or manage changes resulting from anthropogenic pressures. These observations, while complex expensive, required by international scientific, governance policy communities provide baselines against which effects human pressures climate change may be measured reported, resources allocated implement solutions. To identify...
Background ARGOS satellite telemetry is one of the most widely used methods to track movements free-ranging marine and terrestrial animals fundamental studies foraging ecology, migratory behavior habitat-use. location estimates do not include complete error estimations, for many organisms, commonly acquired locations (Location Class 0, A, B, or Z) are provided with no declared estimate. Methodology/Principal Findings We compared accuracy those obtained using Fastloc GPS from same electronic...
Measurements of the status and trends key indicators for ocean marine life are required to inform policy management in context growing human uses resources, coastal development, climate change. Two synergistic efforts identify specific priority variables monitoring: Essential Ocean Variables (EOVs) through Global Observing System (GOOS), Biodiversity (EBVs) from Group on Earth Observations Observation Network (GEO BON). Both systems support reporting against internationally agreed...
The mesopelagic zone of the northeast Pacific Ocean is an important foraging habitat for many predators, yet few studies have addressed factors driving basin-scale predator distributions or inter-annual variability in and breeding success. Understanding these processes critical to reveal how conditions at sea cascade population-level effects. To begin addressing challenging questions, we collected diving, tracking, success, natality data 297 adult female northern elephant seal migrations...

The Global Ocean Observing System (GOOS) and its partners have worked together over the past decade to break down barriers between open-ocean coastal observing, scientific disciplines, operational research institutions. Here we discuss some GOOS successes challenges from decade, present ideas for moving forward, including highlights of 2030 Strategy published in 2019. OceanObs'09 meeting Venice 2009 resulted a remarkable consensus on need common set guidelines global ocean observing...
Abstract Bio‐logging data obtained by tagging animals are key to addressing global conservation challenges. However, the many thousands of existing bio‐logging datasets not easily discoverable, universally comparable, nor readily accessible through repositories and across platforms, slowing down ecological research effective management. A set universal standards is needed ensure discoverability, interoperability translation into management recommendations. We propose a standardisation...
Summary 1. Identification of foraging behaviour and the ability to assess success is critical understanding individual between‐species variation in habitat use ecology. For pelagic predators, behaviour‐dependent metrics are commonly used identify important areas, yet few these have been validated. 2. Using northern elephant seal as a model species, we validated behaviour‐independent measure (changes drift rate) at scale entire migration, then this variety common that based on movement...
SUMMARY The range of foraging behaviors available to deep-diving, air-breathing marine vertebrates is constrained by their physiological capacity breath-hold dive. We measured body oxygen stores (blood volume and muscle myoglobin) diving behavior in adult female northern elephant seals, Mirounga angustirostris, investigate age-related effects on performance. Blood averaged 74.4±17.0 liters seals or 20.2±2.0% mass. Plasma 32.2±7.8 8.7±0.7% Absolute plasma blood increased independently with...
Mass stranding of several species beaked whales (family Ziphiidae) associated with exposure to anthropogenic sounds has raised concern for the conservation these species. However, little is known about species' life histories, prey or habitat requirements. Without this knowledge, it becomes difficult assess effects sound, since there no way determine whether disturbance impacting physical environmental Here we take a bioenergetics approach address gap in our as elusive, deep-diving nature...
Understanding the diet of deep-diving predators can provide essential insight to trophic structure mesopelagic ecosystem. Comprehensive population-level estimates are exceptionally difficult obtain for elusive marine due logistical challenges involved in observing their feeding behavior and collecting samples traditional stomach content or fecal analyses. We used quantitative fatty acid signature analysis (QFASA) estimate composition a wide-ranging predator, northern elephant seal (Mirounga...
Developing enduring capacity to monitor ocean life requires investing in people and their institutions build infrastructure, ownership, long-term support networks. International initiatives can enhance access scientific data, tools methodologies, develop local expertise use them, but without ongoing engagement may fail have lasting benefit. Linking development technology transfer sustained monitoring is a win-win proposition. Trained experts will benefit from joining global communities of...
Marine animals equipped with biological and physical electronic sensors have produced long-term data streams on key marine environmental variables, hydrography, animal behavior ecology. These are an essential component of the Global Ocean Observing System (GOOS). The Animal Borne Sensors (AniBOS) network aims to coordinate collection delivery streams, providing a complementary capability other GOOS networks that monitor Essential Variables (EOVs), climate variables (ECVs) biodiversity...
Marine protected areas (MPAs), particularly large MPAs, are increasing in number and size around the globe part to facilitate conservation of marine megafauna under assumption that large-scale MPAs better align with vagile life histories; however, this alignment is not well established. Using a global tracking dataset from 36 species across five taxa, chosen reflect span home range highly mobile megafauna, we show most too small encompass complete ranges species. Based on alone, 40% existing...
Widely ranging marine predators often adopt stereotyped, energy-saving behaviours to minimize the energetic cost of transport while maximizing energy gain. Environmental and anthropogenic disturbances can disrupt balance by prompting avoidance that increase costs, thereby decreasing foraging efficiency. We examined ability 12 free-ranging, juvenile northern elephant seals (Mirounga angustirostris) mitigate effects experimentally increased costs modifying their behaviour and/or use in a...
Animal telemetry is the science of elucidating movements and behavior animals in relation to their environment or habitat. Here, we focus on aquatic species (marine mammals, sharks, fish, sea birds turtles) so are concerned with animal as they move through above world's oceans, coastal rivers, estuaries great lakes. devices ("tags") yield detailed data regarding responses coupled ocean–atmosphere physical which moving. has matured describe a developing US Telemetry Network (ATN) observing...
Development of global ocean observing capacity for the biological EOVs is on cusp a step-change. Current to automate data collection and processing integrate resulting streams with complementary data, openly available as FAIR certain dramatically increase amount quality information knowledge scientists decision makers into future. There little doubt that will continue expand their understanding what lives in ocean, where it how changing. However, whether this expanding stream inform policy...
Assessing cumulative effects of human activities on ecosystems is required by many jurisdictions, but current science cannot meet regulatory demands. Regulations define them as effect(s) one action combined with other actions. Here we argue for an approach that evaluates the risk multiple stressors protected wildlife populations within their ecosystems. Monitoring each stressor necessary not sufficient to estimate how interact affect populations. Examining mechanistic pathways, from cellular...

An understanding how body changes fine spatial temporal as result interaction with the environment provides necessary information about animals acquire resources. 2. However, comparatively little is known intra- interindividual variation marine systems. Where has been studied, typically are recorded relatively coarse time-scales. By quantifying...
