Animal Borne Ocean Sensors – AniBOS – An Essential Component of the Global Ocean Observing System

Marine animals equipped with biological and physical electronic sensors have produced long-term data streams on key marine environmental variables, hydrography, animal behavior and ecology. These data are an essential component of the Global Ocean Observing System (GOOS). The Animal Borne Ocean Sensors (AniBOS) network aims to coordinate the long-term collection and delivery of marine data streams, providing a complementary capability to other GOOS networks that monitor Essential Ocean Variables (EOVs), essential climate variables (ECVs) and essential biodiversity variables (EBVs). AniBOS augments observations of temperature and salinity within the upper ocean, in areas that are under-sampled, providing information that is urgently needed for an improved understanding of climate and ocean variability and for forecasting. Additionally, measurements of chlorophyll fluorescence and dissolved oxygen concentrations are emerging. The observations AniBOS provides are used widely across the research, modeling and operational oceanographic communities. High latitude, shallow coastal shelves and tropical seas have historically been sampled poorly with traditional observing platforms for many reasons including sea ice presence, limited satellite coverage and logistical costs. Animal-borne sensors are helping to fill that gap by collecting and transmitting in near real time an average of 500 temperature-salinity-depth profiles per animal annually and, when instruments are recovered (∼30% of instruments deployed annually, n = 103 ± 34), up to 1,000 profiles per month in these regions. Increased observations from under-sampled regions greatly improve the accuracy and confidence in estimates of ocean state and improve studies of climate variability by delivering data that refine climate prediction estimates at regional and global scales. The GOOS Observations Coordination Group (OCG) reviews, advises on and coordinates activities across the global ocean observing networks to strengthen the effective implementation of the system. AniBOS was formally recognized in 2020 as a GOOS network. This improves our ability to observe the ocean’s structure and animals that live in them more comprehensively, concomitantly improving our understanding of global ocean and climate processes for societal benefit consistent with the UN Sustainability Goals 13 and 14: Climate and Life below Water. Working within the GOOS OCG framework ensures that AniBOS is an essential component of an integrated Global Ocean Observing System.

“…This protocol has allowed testing of the independence assumption for the period where flipper tagging and branding overlapped (McMahon and White 2009). However, branding is logistically impractical at Marion Island and this technique incorporates animal welfare concerns (Jabour Green and Bradshaw 2004) that resulted in the termination of the Macquarie Island southern elephant seal monitoring program (McMahon et al 2006b(McMahon et al , 2007. Passive integrated transponder (PIT) tags have been used successfully to mark numerous species (Gibbons and Andrews 2004) including southern elephant seals (Galimberti et al 2000).…”

Marker‐loss is a common feature of mark–recapture studies and important as it may bias parameter estimation. A slight alteration in tag‐site of double tagged southern elephant seals (Mirounga leonina), marked at Marion Island from 1983 to 2005 in an ongoing mark–recapture program, had important consequences for tag‐loss. We calculated age‐specific tag‐retention rates and cumulative tag‐retention probabilities using a maximum likelihood model selection approach in the software application TAG_LOSS 3.2.0. Under the tag‐loss independence assumption, double tag‐loss of inner interdigital webbing tags (IIT; 17 cohorts) remained below 1% in the first 5 yr and increased monotonically as seals aged, with higher tag‐loss in males. Lifetime cumulative IIT tag‐loss was 11.9% for females and 18.4% for males, and equivalent for all cohorts. Changing the tag‐site to the outer interdigital webbing (OIT; 6 cohorts) resulted in increased and cohort‐dependent tag‐loss, although the variation (mean ± 95% CI) in cumulative tag‐loss probabilities never exceeded 5.3% between cohorts at similar age. Although different studies may homogenize techniques, we advocate the importance of data set‐specific assessment of tag‐loss rates to ensure greatest confidence in population parameters obtained from mark–recapture experiments. Permanent marking should be implemented where feasible.

“…Information on breeding biology and reproductive performances of avian species constitutes a central part in the understanding of their population bio-ecology and adaptation, as it permits the academics and wild defenders to identify problems [1,2]. Equally, it has direct implications in conservation procedures [3]. On the other hand, the study of breeding biology allows to estimate breeding success and productivity, which are likely useful in population dynamics.…”

The European serin (Serinus serinus) is one of the best examples of a species in the western Palaearctic that has expanded its distribution ranges in current periods. However, the breeding features of serin are not well known and were restricted for some localities, as well as there have not been any deep and comparable studies on its mortality and menacing factors. This study investigates breeding biology, including breeding chronology, nesting strategies, and reproductive success of the European serin in farmland and woodland habitats at Moulouya high plain (Morocco), during 2016. Results showed that, at high-altitude breeding habitats, the European serin started breeding activity lately by 25 April (construction of the first nest) and continued until 19 July (last fledging date). Moreover, most nests (96.42%) were found in farmlands, mainly in apple orchards. Two broods were recorded between April-May and June-July, and the clutch size was an average of 3.04 ± 0.13 eggs/nest. For reproductive success, among the 65 examined nests, 73.84% were active during the nest construction phase and 87.42% of eggs have succeeded during the incubation phase. Reproductive success was higher (93.83%) during fledging. Clutches were failed due to predation (15.9%), nest desertion (14.35%), and destruction of nests (8.88%). Finally, our study highlights that the European serin breeds in high-altitude zones with late and shorter breeding seasons, which might allow this bird to avoid high lands’ vigorous climate conditions and their eﬀect on breeding success.
