“…Studies that include inorganic weathering processes within High-Arctic watersheds provide knowledge about chemical denudation and give estimates of solute yields entering High-Arctic fjords (see, e.g., Hodson et al 2000;Krawczyk et al 2003;Krawczyk & Pettersson 2007;Krawczyk & Bartoszewski 2008). The matter whether such research, based upon one or at most two consecutive ablation seasons, is sufficient and representative of a long-term changes has been somehow overlooked.…”

“…The maximum discharge was in August, with two peak discharges of 2.8 and 3.8 m 3 s −1 . The total volume of water discharged by Scottelva during the re− cording period was 7.92 million m 3 , 22% more than the mean for 1986-2001 (6.46 million m 3 ) (Krawczyk and Bartoszewski 2008). Such a big discharge re− sulted from intensive ablation of Scottbreen, associated with heavy precipitation between 16 th and 27 th August (23 mm) and higher air temperatures than usual (5.5-7.5°C).…”

A 6 km long stretch of the coast of Calypsostranda between Skilvika and Joseph− bukta, situated on the western side of Recherchefjorden, was investigated. It is made of an accumulative marine terrace at a height of 2-8 m a.s.l. (terrace 1) and width of 40-180 m, divided by a cliffed section in the frontal moraines of Renardbreen. From the character and intensity of changes, the area was divided into 6 zones. The aim was to analyse the dynamics of changes within coastal zone from 1936 to 2007 and to characterise the influence of vari− ous morphogenetic factors (marine, fluvial, cryospheric). The important element of this study has been to determine sources and directions of sediment transport. The dynamics of changes of coastal zone in the Calypsostranda region was established from archival maps and precise GPS measurements for the periods: 1936-1960, 1960-1990, 1990-2000, 2000-2005, 2005-2006, 2006-2007. Comparing the extension of shoreline between 1936 and 2007 showed that there was more erosion than accumulation. Nearly 110 000 m 2 of the area of terrace 1 decreased, whereas about 77 000 m 2 appeared. The net balance for 1936-2007 was about −32 700 m 2 , on average over the whole length of the shoreline, it re− treated by 5.7 m (0.08 m a −1 ). The cease of sediment delivery in the extramarginal sandur fans area of Renardbreen caused intensification of marine processes, that made the shore− line retreat by over 100 m. Continuing sediment delivery from the Scottelva catchment, with contribution of material from erosion of the north end of the shoreline studies, caused the aggradation of coastal zone by over 60 m near its mouth.

“…Also, the hydrochemical aspects of chemical denudation generated by cryochemical processes in the glacierized and non-glacierized areas was carried out. The results of these studies were recently published by, among many others, Hodson et al (2000Hodson et al ( , 2002, Cooper et al (2002), Kokelj and Burn (2003), Chmiel et al (2007Chmiel et al ( , 2011Chmiel et al ( , 2012, Krawczyk and Pettersson (2007), Krawczyk and Bartoszewski (2008), Zwoliński et al (2008Zwoliński et al ( , 2012, Bring and Destouni (2009), Dragon and Marciniak (2010), Kuhry et al (2010), Mazurek et al (2012) and Szpikowski et al (2014b).

The paper presents the results of hydrogeochemical and biogeochemical studies in the area of Kaffiøyra river catchments in the ablation season 2004. Vegetation, hydrological regime, mineralization and ionic composition of circulating waters, rate of annual chemical denudation and biogenic CO 2 content in soil air in relation to the concentration of dissolved and transported HCO 3 -ions were documented. The waters represented the type HCO 3 --SO 4 2--Ca. Most of ions showed a good correlation with electrical conductivity. A good correlation between dissolved and transported mass and the discharge was shown. The value of the chemical denudation in non-glacierized catchments of the Kaffiøyra plain was 0.07 and 0.13 t km -2 d -1 , in glacierized catchment -0,21 t km -2 d -1. The biogenic CO 2 concentrations in tundra soil air ranged from 0.03-0.08%, while the average was 0.046%. The mean rate of CO 2 ionic transport was 3 kg d -1 , while of HCO 3 --0.63 t d -1. A low correlation between the concentration of biogenic CO 2 in soil air and HCO 3 -was found, which indicates the involvement of other, unexamined bio-and physico-chemical processes.
