New insights from XRF core scanning data into boreal lake ontogeny during the Eemian (Marine Isotope Stage 5e) at Sokli, northeast Finland

Biological proxies from the Sokli Eemian (Marine Isotope Stage 5e) paleolake sequence from northeast Finland have previously shown that, unlike many postglacial records from boreal sites, the lake becomes increasingly eutrophic over time. Here, principal components (PC) were extracted from a high resolution multi-element XRF core scanning dataset to describe minerogenic input from the wider catchment (PC1), the input of S, Fe, Mn, and Ca-rich detrital material from the surrounding Sokli Carbonatite Massif (PC2), and chemical weathering (PC3). Minerogenic inputs to the lake were elevated early in the record and during two abrupt cooling events when soils and vegetation in the catchment were poor. Chemical weathering in the catchment generally increased over time, coinciding with higher air temperatures, catchment productivity, and the presence of acidic conifer species. Abiotic edaphic processes play a key role in lake ontogeny at this site stemming from the base cation- and nutrient-rich bedrock, which supports lake alkalinity and productivity. The climate history at this site, and its integrated effects on the lake system, appear to override development processes and alters its long-term trajectory.

Grammar of Skolt Saami

Skolt Saami is a Finno-Ugric language spoken primarily in northeast Finland by less than 300 people. The aim of this descriptive grammar is to provide an overview of all the major grammatical aspects of the language. It comprises descriptions of Skolt Saami phonology, morphophonology, morphology, morphosyntax and syntax. A compilation of interlinearised texts is provided in Chapter 11. Skolt Saami is a phonologically complex language, displaying contrastive vowel length, consonant gradation, suprasegmental palatalisation and vowel height alternations. It is also well known for being one of the few languages to display three distinctive degrees of quantity; indeed, this very topic has already been the subject of an acoustic analysis (McRobbie-Utasi 1999). Skolt Saami is also a morphologically complex language. Nominals in Skolt Saami belong to twelve different inflectional classes. They inflect for number and nine grammatical cases and may also mark possession, giving rise to over seventy distinct forms. Verbs belong to four different inflectional classes and inflect for person, number, tense and mood. Inflection is marked by suffixes, many of which are fused morphemes. Other typologically interesting features of the language, which are covered in this grammar, include (i) the existence of distinct predicative and attributive forms of adjectives, (ii) the case-marking of subject and object nominals which have cardinal numerals as determiners, and (iii) the marking of negation with a negative auxiliary verb. Skolt Saami is a seriously endangered language and it is thus hoped that this grammar will serve both as a tool to linguistic researchers and as an impetus to the speech community in any future revitalisation efforts.
