Lagrangian ocean analysis: Fundamentals and practices

Ocean Modelling, Journal Year: 2017, Volume and Issue: 121, P. 49 - 75

Published: Nov. 24, 2017

Lagrangian analysis is a powerful way to analyse the output of ocean circulation models and other velocity data such as from altimetry. In approach, large sets virtual particles are integrated within three-dimensional, time-evolving fields. Over several decades, variety tools methods for this purpose have emerged. Here, we review state art in field data, starting fundamental kinematic framework with focus on large-scale open applications. Beyond use explicit fields, consider influence unresolved physics dynamics particle trajectories. We comprehensively list discuss currently available tracking particles. then showcase some innovative applications trajectory conclude questions an outlook. The overall goal paper reconcile different techniques analysis, while recognising rich diversity codes that continue emerge, challenges coming age petascale computing.

Conserving mobile species

Frontiers in Ecology and the Environment, Journal Year: 2014, Volume and Issue: 12(7), P. 395 - 402

Published: July 17, 2014

The distributions of many species are dynamic in space and time, movements made by individuals range from regular predictable migrations to erratic, resource‐driven nomadism. Conserving such mobile is challenging; the effectiveness a conservation action taken at one site depends on condition other sites that may be geographically politically distant (thousands kilometers away or another jurisdiction, for example). Recent work has shown even simple linkages among caused “to‐and‐fro” migration can make migratory especially vulnerable habitat loss, substantially affect results prioritizations. Species characterized more erratic nomadic very difficult protect through current planning techniques, which typically view as static. However, collaborations between ecologists, planners, mathematical ecologists paving way improvements species.

The study of landscape connectivity in conservation has increased considerably since the early part 21st century. While implications are self-evident for conservation, they also important physical geography a proper understanding patterns and processes allows better management practices, which at core geography. This paper presents review literature based on 162 publications from 2000 to 2013, we evaluated current state recent advances integration identification planning areas. data analysis were database organized into five categories: General information, areas, research objectives, methods studies, with conservation.

Parcels v0.9: prototyping a Lagrangian ocean analysis framework for the petascale age

Geoscientific model development, Journal Year: 2017, Volume and Issue: 10(11), P. 4175 - 4186

Published: Nov. 17, 2017

Abstract. As ocean general circulation models (OGCMs) move into the petascale age, where output of single simulations exceeds petabytes storage space, tools to analyse these will need scale up too. Lagrangian analysis, virtual particles are tracked through hydrodynamic fields, is an increasingly popular way OGCM output, by mapping pathways and connectivity biotic abiotic particulates. However, current software stack analysis codes not dynamic enough cope with increasing complexity, for customization use-cases. Furthermore, most community developed stand-alone use, making it a nontrivial task integrate at runtime OGCM. Here, we introduce new Parcels code, which was designed from ground be sufficiently scalable computing. We highlight its API design that combines flexibility ability optimize HPC workflows, following paradigm domain-specific languages. primarily written in Python, utilizing wide range available scientific Python ecosystem, while generating low-level C code using just-in-time compilation performance-critical computation. show worked-out example API, validate accuracy against seven idealized test cases. This version 0.9 focused on laying out future work concentrating support curvilinear grids, optimization, efficiency at-runtime coupling OGCMs.

Summary The successful movement of individuals is fundamental to life. Facilitating these movements by promoting ecological connectivity has become a central theme in ecology and conservation. Urban areas contain more than half the world's human population, their potential support biodiversity connect citizens nature increasingly recognized. Promoting within essential reaching this potential. However, our current understanding urban appears limited. We reviewed published scientific literature assess state‐of‐the‐art research areas, summarized trends study attributes highlighted knowledge gaps. found 174 papers that investigated areas. These addressed either structural (48) or functional (111), some both (15), but contained substantial geographic taxonomic biases. rarely defined aspect they were investigating objective descriptions local context uncommon. Formulated hypotheses priori predictions typically unstated many used suboptimal designs methods. suggest future studies explicitly consider quantify landscape analyses make greater use available rapidly developing tools methods for measuring (e.g. biotelemetry genetics). also highlight need clearly define how terms ‘ ’ have been applied. Knowledge gaps remain, partly because field still its infancy we must better capitalize on technological analytical techniques are available.

Estimating dispersal distance in the deep sea: challenges and applications to marine reserves

Frontiers in Marine Science, Journal Year: 2015, Volume and Issue: 2

Published: Feb. 13, 2015

Population connectivity refers to the exchange of individuals among populations: it affects gene flow, regulates population size and function, mitigates recovery from natural or anthropogenic disturbances. Many populations in deep sea are spatially fragmented, will become more so with increasing resource exploitation. Understanding is critical for spatial management. For most benthic species, achieved by planktonic larval stage, dispersal is, turn, regulated complex interactions between biological oceanographic processes. Coupled biophysical models, incorporating ocean circulation traits, such as duration (PLD), have been used estimate generate management plans coastal shallow waters. In sea, knowledge gaps both physical components delaying effective use this approach. Here, we review current efforts conservation evaluate (1) relevance using design marine protected areas (2) application models study connectivity. Within PLD can be distance. We propose that a guarantees minimum distance wide range species should planning sea.
