To address this gap, three cruises were conducted in the Kara Sea from late June to early August during sea ice retreat. The present study focused on the variability of primary production (PP), chlorophyll-<em>a</em> (Chl-<em>a</em>) concentration of total and size-fractionated phytoplankton, the evolution of the subsurface Chl-<em>a</em> maximum layer (SCML), and its contribution to the total water column PP (IPP_tot) and integrated photosynthetic layer Chl-<em>a</em> (Chl_ph). During the study period, the ice-edge phytoplankton bloom was characterised by high values of IPP_tot and Chl_ph (up to 1352 mgC m⁻² d^–1 and 151.53 mg m⁻², respectively) and a dominance of microphytoplankton (&gt;20 µm) in the water column (88 % of IPP_tot and 77 % of Chl_ph on average) and in the SCML (52 % of PP and 64 % of Chl-<em>a</em> on average). The role of nano- (3 – 20 µm) and picophytoplankton (&lt;3 µm) increased with sea ice retreat. During the melt season, micro-, nano- and picophytoplankton contributed on average 50, 14 and 36 % to IPP_tot and 60, 15 and 25 % to Chl_ph, respectively. PP and Chl-<em>a</em> associated with the SCML contributed 32 % to IPP_tot and 76 % to Chl_ph. The rapid decline in IPP_tot during sea ice retreat suggests that Arctic warming, sea ice loss, and the significant increase in total PP due to newly exposed open water areas may not be accompanied by an increase in photosynthetic activity in the Arctic Ocean. During the ice melt season in the Kara Sea ∼1/3 of IPP_tot and 3/4 of Chl_ph are concentrated in the SCML, emphasizing its importance in the seasonal trophic balance and in the development of PP algorithms.</div></div>","PeriodicalId":20620,"journal":{"name":"Progress in Oceanography","volume":"241 ","pages":"Article 103652"},"PeriodicalIF":3.6,"publicationDate":"2025-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145785777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was conducted on the adjacent shelf and in Kongsfjorden, a high-Arctic fjord system in Svalbard, where the Kongsfjorden Transect (KT), influenced by Arctic and Atlantic oceanic regimes, shows strong variability in physico-chemical conditions. Consequently, changes in environmental conditions, including the depth of the halocline, can act as a physical barrier for organisms, affecting local biodiversity. We, investigated meroplankton vertical distribution in relation to the halocline, and hypothesized that the salinity gradient acts as a barrier for larvae, influencing their movements, distribution and diversity. We identified 25 meroplankton morphotypes along the KT, with Bivalvia veligers as the dominant taxon. Taxonomic assemblages differed significantly between above (AH) and below (BH) the halocline. More abundant Echinodermata larvae characterized the AH assemblage, which remained compositionally similar throughout the studied transect. In contrast, Polychaeta larvae were characteristic of the BH assemblage with greater spatial variability, consistent with decreasing temperature, salinity, and chlorophyll <ce:italic>a</ce:italic> concentration, towards the inner part of the fjord. By integrating detailed morphotype analysis with hydrographic data, we showed that the halocline is a barrier for meroplankton larvae, defining their vertical distribution, abundance, and taxonomic composition; we also present the indicator taxa of the AH and BH assemblages. Our results emphasize the role of the salinity gradient in shaping larval communities and support their potential role as early indicators of environmental change in the Arctic fjords.","PeriodicalId":20620,"journal":{"name":"Progress in Oceanography","volume":"7 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145759816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lagoon is connected to the open ocean through shallow reef flats along the northwestern and western rims, and a 40 m deep channel in the northern rim. Spatiotemporal variability of lagoon hydrodynamics is characterized with a 15-year (2009–2023) simulation of a high-resolution ocean-wave coupled model. In winter, strong northeasterly winds generate high waves that approach the atoll from the northeast, breaking on the reef flats to the northwest of the lagoon, and driving strong flow across the reef flats into the lagoon. The wave- and wind-driven flows together forms a counterclockwise vortex pattern over the entire water column in the western lagoon, leading to a strong barotropic outflow through the deep channel. The lagoon circulation in winter is thus <em>laterally sheared</em>. In summer with weaker northeasterly winds, the wave-driven overflow across the northwestern reef flats weakens. In fall, episodic westerly winds drive open ocean water across the western reef flat into the lagoon. The weak winds in summer and fall allow the development of <em>vertically sheared</em> flows in the lagoon, with surface flows generally aligned with winds and subsurface flows opposing winds. This study demonstrates that lagoon circulation, varying over the scale of O(100 m-10 km), differ drastically from that in the surrounding ocean, can directly affect coral reef communities, and is thus critical for effective marine resource management.</div><div>Plain language summary.</div><div>Majuro Atoll, Republic of Marshall Islands, is located in the Central Pacific and is made up of rim reefs and islands surrounding lagoon of 40 km long and 10 km wide. The lagoon is separated from the open ocean by shallow rim reefs on its north and west sides and an island chain on its south and east sides. The deep part of the lagoon is connected to the open ocean by a 40-m deep channel in the north. This work uses a high-resolution computer model to simulate flows and temperature conditions in 2009–2023 and study how the lagoon flow conditions change in space and time. The model shows that the lagoon flows are influenced not only by winds throughout the year but also by high waves approaching the atoll from the northeast. As the waves break on the north shore of the atoll, they push a significant amount of water into the lagoon. Some of the lagoon water then flow out into the open ocean through the deep channel. Circulation in the lagoon changes dramatically with the winds. All these flow changes in the lagoon cause the lagoon environment to differ significantly from the open ocean. Such fine-scale changes in lagoon conditions likely affect coral health, influence their responses to climate change, and provide key information for effective coral reef conservation and protection.</div></div>","PeriodicalId":20620,"journal":{"name":"Progress in Oceanography","volume":"241 ","pages":"Article 103648"},"PeriodicalIF":3.6,"publicationDate":"2025-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145732113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
