Abstract Although the evolutionary and ecological processes that contribute to plant invasion have been focus of much research, investigation into molecular basis is just beginning. Common ragweed ( A mbrosia artemisiifolia ) an annual weed native North merica has introduced E urope where it become invasive. Using a custom‐designed N imble G en oligoarray, we examined differences in gene expression between five six populations common three different environments (control, light stress...
Overflow water from the Nordic Seas comprises deepest limb of Atlantic Meridional Overturning Circulation, yet questions remain as to where it is ventilated and how reaches Greenland-Scotland Ridge. Here we use historical hydrographic data 2005-2015, together with satellite altimeter data, elucidate source regions Denmark Strait Faroe Bank Channel overflows pathways feeding these respective sills. A recently-developed metric used calculate similar two parcels are, based on potential density...
Abstract In recent years, blooms of the neurotoxic dinoflagellate Alexandrium catenella have been documented in Pacific Arctic waters, and paralytic shellfish toxins (PSTs) that this species produces detected throughout food web. These observations raised significant concerns about role harmful algal (HABs) will play a rapidly changing Arctic. During research cruise summer 2022, massive bloom A. was real time as it advected through Bering Strait region. The exceptional both spatial scale...
Abstract Ocean eddies were widely reported to strongly impact near‐surface chlorophyll (CHL), but most of previous studies are confined the ocean surface. Based on large‐scale historical cruise observations with mesoscale detected by altimeters in North Pacific, we show that depth‐integrated nitrate and anomalies euphotic layer less than ±90% for ±10% chlorophyll. These eddy‐driven variations decline from boundaries open ocean, due a combination effect eddy activity subsurface distribution....
Abstract The Iceland Greenland Seas Project (IGP) is a coordinated atmosphere–ocean research program investigating climate processes in the source region of densest waters Atlantic meridional overturning circulation. During February and March 2018, field campaign was executed over southern that utilized range observing platforms to investigate critical region, including vessel, aircraft, moorings, sea gliders, floats, meteorological buoy. A remarkable feature highly deployment platforms,...
Abstract Dissolved organic nitrogen (DON) is the dominant form of fixed in most low and middle latitude ocean surface waters. Here, we report measurements DON isotopic composition (δ 15 N) from west South China Sea (SCS), with goal providing new insight into cycling. The concentration correlated ( r = 0.70, p < 0.0001) chlorophyll a concentration, indicating production these δ N fall relatively narrow range (4.6 ± 0.1 μM 4.3 0.2‰ vs. air, respectively; SD ), similar to other regions. mean...
The flow of Pacific-origin water across the Chukchi Sea shelf impacts regional ecosystem in profound ways, yet two current branches on eastern that carry from Bering Strait to Barrow Canyon – Alaskan Coastal Current (ACC) and Central Channel (CC) Branch have not been clearly distinguished or quantified. In this study we use an extensive collection repeat hydrographic sections occupied at three locations shelf, together with data a climatology shipboard velocity data, accomplish this. were...
Summary Introduced plants may quickly evolve new adaptive traits upon their introduction. Canada thistle ( Cirsium arvense – Cardueae, Asteraceae) is one of the worst invasive weeds worldwide. The goal this study to compare gene expression profiles native (European) and introduced (North American) populations species, elucidate genetic mechanisms that underlie such rapid adaptation. We explored transcriptome ten (five per range) C. in response three treatments (control, nutrient deficiency...
Abstract Temporal evolution of near‐surface chlorophyll (CHL) associated with mesoscale eddies over entire eddy lifespan is complicated. Based on satellite measurements and a reanalysis data set, we identify quantify major temporal spatial CHL responses in cyclonic the southeastern Pacific, explore mechanisms. Only few variations can be directly linked to four primary mechanisms: “eddy pumping,” trapping,” stirring,” “eddy‐induced Ekman pumping.” About 80% are too complex explained by single...
The warm-to-cold densification of Atlantic Water (AW) around the perimeter Nordic Seas is a critical component Meridional Overturning Circulation (AMOC). However, it remains unclear how ongoing changes in air-sea heat flux impact this transformation. Here we use observational data, and one-dimensional mixing model following flow, to investigate role on cooling AW. We focus Norwegian Slope Current (NwASC) Front (NwAFC), where primary transformation AW occurs. find that accounts almost...
Abstract Hydrographic and velocity data from a 2018 winter survey of the western Iceland Greenland Seas are used to investigate ventilation overflow water feeding Denmark Strait. We focus on two general classes water: warm, saline Atlantic‐origin Overflow Water (AtOW) cold, fresh Arctic‐origin (ArOW). The former is found predominantly within East Current (EGC), while latter resides in interior Seas. Progressing north south, properties AtOW EGC modified diapycnally during winter, contrast...
Abstract Mesoscale eddies may enhance nutrient injection into the photic zone and ultimately magnitude composition of particle export to depth. Using satellite altimetry, we identified 38 cyclonic that passed in close proximity Hawaii Ocean Time‐series (HOT) Station ALOHA, located North Pacific Subtropical Gyre, from 1993 2018. Particulate carbon (C), nitrogen (N), biogenic silica (Si) rates, measured using free floating sediment traps deployed at 150 m as part HOT, were then associated with...
Zn is an essential trace element required for maintaining normal growth and development. deficiency can cause retardation reproductive system dysplasia, while supplementation treating requires the use of high-quality preparations. In this study, Bifidobacterium longum CCFM1195 was screened its high enrichment capacity, effects different regimens doses on development rats after were investigated by supplementing Zn-deficient rat pups with various supplements (ZnO, + ZnO, Zn-enriched...
Abstract Marine cold‐air outbreaks (CAOs) are vigorous equatorward excursions of cold air over the ocean, responsible for majority wintertime oceanic heat loss from subpolar seas North Atlantic. However, impact individual CAO events on ocean is poorly understood. Here we present first coupled observations atmosphere and during a event, between 28 February 13 March 2018, in Atlantic region. Comprehensive presented five aircraft flights, research vessel, meteorological buoy, subsurface...
Abstract Mooring data from September 2011 to July 2013 on the Iceland slope north of Denmark Strait are analyzed better understand structure and variability North Icelandic Jet (NIJ). Three basic configurations flow were identified: (1) a strong separated East Greenland Current (EGC) mid‐Iceland coincident with weak NIJ upper slope, (2) merged EGC NIJ, (3) located at its climatological mean position, signature base slope. Our study reveals that NIJ‐dominant scenario was present during...
A novel composite monolithic cryogel embedded with nanogels was synthesized by incorporating poly(glycidyl methacrylate) into a poly(acrylamide) matrix, followed grafting (vinylbenzyl)trimethylammonium chloride. The nanogel-based cryogels prepared under various conditions were characterized and employed for chromatographic separation of bovine serum albumin (BSA) from crude serum. results indicated that these have high porosity, permeability weak axial dispersion properties. They exhibited...
Abstract In order to quantify pelagic‐benthic coupling on high‐latitude shelves, it is imperative identify the different physical mechanisms by which phytoplankton are exported sediments. June–July 2023, a field program documented evolution of an under‐ice bloom northeast Chukchi shelf. Here, we use in situ data from cruise, simple numerical model, historical water column data, and ocean reanalysis fields characterize setting describe dynamically driven vertical export chlorophyll associated...
Abstract Barrow Canyon in the northeast Chukchi Sea is a critical choke point where Pacific‐origin water, heat, and nutrients enter interior Arctic. While flow through canyon has been monitored for more than 20 years, questions remain regarding dynamics by which water fluxed offshore, as well what drives variability. In 2018, two high‐resolution shipboard surveys of were carried out—one summer one fall—to investigate mass distribution velocity structure outflow. During survey, high...
