title: Carbon flux from aquatic ecosystems of the Arctic Coastal Plain along the Beaufort Sea, Alaska, 2010-2018

description: Multiple aquatic ecosystems (pond, lake, river, lagoon, ocean) on the
  Arctic Coastal Plain (ACP) near Utqiaġvik, Alaska, USA were visited to
  determine their relative contribution to landscape-level atmospheric
  carbon dioxide (CO2) flux and how this may have changed over time. pCO2 (partial
  pressure of carbon dioxide) was monitored in late summer (late July to
  mid-August) over a period of four years (2013, 2015, 2017, 2018) from
  open water areas and is related to habitat type, dissolved organic
  carbon (DOC) and environmental factors (temperature, radiation,
  rainfall). Data include both daily averages from most sites, as well
  as spatial representation of pCO2 in Elson Lagoon and diel cycles of
  pCO2 from a tundra pond. Pond net ecosystem production (NEP) is
  estimated by free water metabolism and presented as daily estimates
  over a four summer period.

title: The Cosmogrid Simulation: Statistical Properties of Small Dark Matter Halos (2048-504)

description: We present the results of the "Cosmogrid" cosmological N-body simulation suites based on the concordance LCDM model. The Cosmogrid simulation was performed in a 30 Mpc box with 2048³ particles. The mass of each particle is 1.28x10^5 Msun, which is sufficient to resolve ultra-faint dwarfs. We found that the halo mass function shows good agreement with the Sheth & Tormen fitting function down to ~10^7 Msun. We have analyzed the spherically averaged density profiles of the three most massive halos which are of galaxy group size and contain at least 170 million particles. The slopes of these density profiles become shallower than -1 at the inner most radius. We also find a clear correlation of halo concentration with mass. The mass dependence of the concentration parameter cannot be expressed by a single power law, however a simple model based on the Press-Schechter theory proposed by Navarro et al. gives reasonable agreement with this dependence. The spin parameter does not show a correlation with the halo mass. The probability distribution functions for both concentration and spin are well fitted by the log-normal distribution for halos with the masses larger than ~10^8 Msun. The subhalo abundance depends on the halo mass. Galaxy-sized halos have 50% more subhalos than ~10^11 Msun halos have. This is snapshot 504 of the 2048³ resolution collection.

The spin parameter does not show a correlation with the halo mass. The probability distribution functions for both concentration and spin are well fitted by the log-normal distribution for halos with the masses larger than ~10^8 Msun. The subhalo abundance depends on the halo mass. Galaxy-sized halos have 50% more subhalos than ~10^11 Msun halos have. This is snapshot 517 of the 2048³ resolution collection.

title: The Cosmogrid Simulation: Statistical Properties of Small Dark Matter Halos (2048-505)

description: We present the results of the "Cosmogrid" cosmological N-body simulation suites based on the concordance LCDM model. The Cosmogrid simulation was performed in a 30 Mpc box with 2048³ particles. The mass of each particle is 1.28x10^5 Msun, which is sufficient to resolve ultra-faint dwarfs. We found that the halo mass function shows good agreement with the Sheth & Tormen fitting function down to ~10^7 Msun. We have analyzed the spherically averaged density profiles of the three most massive halos which are of galaxy group size and contain at least 170 million particles. The slopes of these density profiles become shallower than -1 at the inner most radius. We also find a clear correlation of halo concentration with mass. The mass dependence of the concentration parameter cannot be expressed by a single power law, however a simple model based on the Press-Schechter theory proposed by Navarro et al. gives reasonable agreement with this dependence. The spin parameter does not show a correlation with the halo mass. The probability distribution functions for both concentration and spin are well fitted by the log-normal distribution for halos with the masses larger than ~10^8 Msun. The subhalo abundance depends on the halo mass. Galaxy-sized halos have 50% more subhalos than ~10^11 Msun halos have. This is snapshot 505 of the 2048³ resolution collection.
