Increasing availability and extent of biological ocean time series (from both in situ satellite data) have helped reveal significant phenological variability marine plankton. The to which the range this is modified as a result climate change obvious importance. Here we summarize recent research results on phenology phytoplankton zooplankton. We suggest directions better quantify monitor future plankton shifts, including (i) examining main mode expected changes (ecological shifts timing...
Abstract A rctic organisms are adapted to the strong seasonality of environmental forcing. small timing mismatch between biological processes and environment could potentially have significant consequences for entire food web. Climate warming causes shrinking ice coverage earlier retreat in rctic, which is likely change primary production. In this study, we test predictions on interactions among sea phenology production algae pelagic phytoplankton. We do so using following (1) a synthesis...
Recent years have seen a rapid expansion in the ability of earth system models to describe and predict physical state ocean. Skilful forecasts ranging from seasonal (3 months) decadal (5-10 years) time scales are now reality. With advance these ocean physics, first generation marine ecological has started emerge. Such potentially great value management living resources for all those who dependent on both nutrition their livelihood; however, this is still field its infancy. We review art...
Decadal‐scale regime shifts in Northwest Atlantic shelf ecosystems can be remotely forced by climate‐associated atmosphere‐ocean interactions the North and Arctic Ocean Basins. This remote climate forcing is mediated primarily basin‐ hemispheric‐scale changes ocean circulation. We review synthesize results from process‐oriented field studies retrospective analyses of time‐series data to document linkages between climate, circulation, ecosystem dynamics. Bottom‐up associated with plays a...
In the past 100 years since birth of fisheries oceanography, research on early life history fishes, particularly larval stage, has been extensive, and much progress made in identifying mechanisms by which factors such as feeding success, predation, or dispersal can influence survival.However, recent years, study fish undergone a major and, arguably, necessary shift, resulting growing body aimed at understanding consequences climate change other anthropogenically induced stressors.Here, we...
abstract The marine coastal region makes up just 10% of the total area global ocean but contributes nearly 20% its primary production and over 80% fisheries landings. Unicellular phytoplankton dominate production. Climate variability has had impacts on various ecosystems, most sites are approaching age at which ecological responses to longer term, unidirectional climate trends might be distinguished. All five pelagic in US Long Term Ecological Research (LTER) network experiencing warming...
The aphorism, ‘All models are wrong, but some useful’, originally referred to statistical models, is now used for scientific in general. When presenting results from a marine simulation model, this statement effectively stops discussions about the quality of as there always another observation mismatch, and thereby confirmation why model cannot be trusted. It common that observations less challenged often viewed ‘gold standard’ judging whereas proper interpretations true value overlooked....
Abstract The North Atlantic Ocean contains diverse patterns of seasonal phytoplankton blooms with distinct internal dynamics. We analyzed using remotely-sensed chlorophyll a concentration data and change point statistics. first bloom the year began during spring at low latitudes later in summer higher latitudes. In regions where occurred high frequency (i.e., proportion years that was detected), there negative correlation between timing duration, indicating early last longer. much Northeast...
The planktonic copepod, Calanus finmarchicus, resides at the southern edge of its subarctic range in Gulf Maine (GoM). Here we investigate population response C. finmarchicus to record warming GoM 2012. Demographic data from two time series stations and a plankton survey conducted early autumn 2012 show that did not produce an generation as predicted, despite warm summer overwintering temperatures. On contrary, observed high abundances stage CV western new cohort spring 2013 likely...
Abstract The Paris Agreement is a multinational initiative to combat climate change by keeping global temperature increase in this century 2°C above preindustrial levels while pursuing efforts limit the 1.5°C. Until recently, ensembles of coupled simulations producing temporal dynamics en route stable mean at 1.5 and were not available. Hence, few studies that have assessed ecological impact used ad‐hoc approaches. development new specific mitigation now provides an unprecedented opportunity...
Abstract Colonially-breeding seabirds have long served as indicator species for the health of oceans on which they depend. Abundance and breeding data are repeatedly collected at fixed study sites in hopes that changes abundance productivity may be useful adaptive management marine resources, but their suitability this purpose is often unknown. To address this, we fit a Bayesian population dynamics model includes process observation error to all known Adélie penguin (1982–2015) Antarctic,...
Abstract Aim One of the primary characteristics that determines structure and function marine food webs is utilization prominence energy‐rich lipids. The biogeographical pattern lipids throughout ocean delineates “lipidscape,” which supports lipid‐rich fish, mammal, seabird communities. While importance well appreciated, there are no synoptic measurements or estimates lipidscape. Productive in pelagic depend on critical diapause stage large copepods, integrate lipid production from...
The northern sand lance ( Ammodytes dubius ), a key species in the food web supporting Stellwagen Bank National Marine Sanctuary (SBNMS), feeds primarily on lipid-rich copepod Calanus finmarchicus . Climate change poses significant threat to this dynamic, as C. populations are at southern edge of their subarctic distribution and vulnerable warming waters changing oceanographic conditions. Declines advective supply could adversely affect and, consequently, ecological economic resources that...
The Arctic cod (Boreogadus saida) is a key species in marine ecosystems, adapted to extreme seasonality and cold environments. overwintering survival recruitment of age-0 heavily depend on achieving sizable prewinter length (PWL) their first year. Over the growth period, PWL influenced by early life history traits, such as hatch date size-at-hatch, environmental conditions, temperature food availability. However, our knowledge these interacting aspects ecology extremely limited. Here we...
Climate change‐induced freshening of the ocean can enhance vertical stratification and alter circulation patterns in ways that influence phytoplankton dynamics. We examined timing spring blooms magnitude net primary productivity Nova Scotian Shelf (NSS) ‐ Gulf Maine (GoM) region with respect to seasonal interannual changes surface water from 1998 2006. The general pattern temporal westward progression bloom corresponds gradient increasing sea salinity NSS east western GoM. Increased enhances...
Remotely sensed ocean color data and numerical modeling have been used to study the phenology of both spring fall phytoplankton blooms (FPBs) in Nova Scotian Shelf (NSS)–Gulf Maine (GoM) region. The reveal a general pattern westward progression bloom (SPB), an eastward FPB NSS–GoM spatial mean chlorophyll concentration is similar that fall, with lower NSS higher GoM. Interannually, there weak but significant tendency for years earlier (delayed) SPBs be followed by delayed (earlier) FPBs,...
In this study, we examine the importance of regional wind forcing in modulating advective processes and hydrographic properties along Northwest Atlantic shelf, with a focus on Nova Scotian Shelf (NSS)-Gulf Maine (GoM) region.Long-term observational data alongshore stress, sea level slope, along-shelf flow are analyzed to quantify relationship between hydrodynamic responses interannual time scales.Additionally, simplified momentum balance model is used underlying mechanisms.Our results show...
