Short summary
The study identified key extreme metocean conditions relevant for Floating Storage and Regasification Unit design on Estonia’s coast, using statistical approaches like GPD and GEV to estimate return values. These thresholds inform infrastructure safety margins. The analysis was extended across the Baltic Sea using harmonized methods, enabling consistent risk assessment, cross-border planning, and climate-resilient design for major maritime infrastructure sites.

Short summary
Surface waves are generated by the wind and wave measurements can also be used to estimate the wind speed. This is beneficial in the open ocean where direct measurements of the wind are difficult. The wind speed deduced from wave measurements serve as a third estimate of the wind speed in addition to satellite measurements or numerical model results. We implemented such and algorithm to be used with wave data from a small buoy and validated it against direct wind measurements and model results.

Short summary
Typical wave statistics do not provide information on how often certain wave heights are exceeded and the length of such events. Our study found a strong seasonal dependence for 2.5 and 4 m wave events in the Baltic Sea. Wave heights of over 7 m occurred less than once per year. The number of 1 m wave events can double within 20 km in nearshore areas. Our results are important for all operations at sea, including ship traffic and fish farming.

Short summary
We analysed the correlation of sea level and wind waves at a coastal location in the Gulf of Finland using tide gauge data, wave measurements, and wave simulations. The correlation was positive for southwesterly winds and negative for northeasterly winds. Probabilities of high total water levels (sea level + wave crest) are underestimated if sea level and waves are considered independent. Suitably chosen copula functions can account for the dependence.

Short summary
Waves that travel faster than the wind are called swell. Our study presents wave model statistics of swell waves in the Baltic Sea, since such statistics have not yet been reliably compiled. Our results confirm that long, high, and persistent swell is absent in the Baltic Sea. We found that the dependency between swell and wind waves differs in the open sea compared to nearshore areas. These distinctions are important for studies on how waves interact with the atmosphere and the sea floor.

Short summary
Coastal ecosystems strongly influence the global carbon cycle but remain poorly quantified. We measured surface pCO₂, CH₄, and N₂O concentrations in southwest Finland across an estuarine ecosystem. Greenhouse gases concentrations varied with salinity and habitat type. Riverine inputs and mixing with seawater, and primary production shaped greenhouse gases dynamics, emphasizing benthic control as a key yet uncertain driver of coastal carbon fluxes.

Using model-simulations and field data, we assess the effect of past eutrophication on present and future ammonium dynamics in coastal sediments of the Baltic Sea and their impact on the coastal ecosystem. Our results indicate a clear eutrophication legacy effect on the persistence of ammonium being released from the sediment to the water column, particularly under oxygen deficiency, with long-lasting effects into the far future and thus important implications for ecosystem recovery measures.

Reed bed carbon (C) storage is a topic of interest due to increased global distribution of reeds. C budgets to combat climate change often catalog reed beds as saltmarshes. Our findings show that reed beds are unique from saltmarshes, C storage is highest in reed bed sediments, and that reed bed zones may impact C storage. Further research into reed bed C is needed to better combat climate change and to ensure reeds are managed in a way that does not release excess C.

Here, we report aerosol properties from a new atmospheric observatory established at the Finnish Baltic Sea Coast. Aerosol formation was observed when air masses crossed over the continent whereas less newly formed particles were observed when the winds were from the sea. Aerosol formation was favoured by low condensation sink and sunny dry conditions.

Non-idealized wind profiles with negative shear in part of the profile (e.g., low-level jets) frequently occur in coastal environments and are important to take into consideration for offshore wind power. Using observations from a coastal site in the Baltic Sea, we analyze in which meteorological and sea state conditions these profiles occur and study how they alter the turbulence structure of the boundary layer compared to idealized profiles.

Every year intense cyanobacterial and macroalgal blooms occur in the Baltic Sea and in the coastal areas surrounding Helsinki, yet no studies have addressed the impact of biogenic emissions from these blooms on gas vapor concentrations, which in turn could influence new particle formation. This is the first study of its kind to address the chemistry driving new particle formation (NPF) during a bloom period in this region, highlighting the role of biogenic sulfuric acid and iodic acid.

Short summary
Ship emissions play an important role in the deposition of gaseous compounds and nanoparticles (Ntot), affecting climate, human health (especially in coastal areas), and eutrophication. Micrometeorological methods showed that ship emissions were mainly responsible for the deposition of Ntot, whereas they only accounted for a minor proportion of CO2 deposition. An uncertainty analysis applied to the fluxes and fuel sulfur content results demonstrated the reliability of the results.

Short summary
Strong motions caused by surface waves can set the material at the bottom in motion. How strong the wave motions need to be depends on the bottom type, for example mud or sand. We estimated how often waves can lift particles from the bottom by comparing wave model results to sea floor samples in the laboratory. We included the effect of seasonal biological activity, which was found to be significant.
