title: Operating speeds for incremental and leapfrog investment strategies in bus-based transit

description: This study compares the leapfrog and incremental approaches taken to improve public transport with an intention of achieving a complete bus rapid transit (BRT) system as the final product. The leapfrog approach is characterised with corridor level uplift following the full specification of Latin American BRTs to replace the existing minibus taxis (MBTs) as evidenced in Cape Town, Johannesburg and Tshwane. The incremental approach was envisaged to involve three interventions starting with scheduling of the existing MBTs, operating scheduled buses in mixed traffic and final introduction of BRT dedicated lanes with median stations. Rustenburg Local Municipality has taken an incremental approach in which the existing MBTs have been scheduled and buses added to enhance capacity on certain routes. This comparison of the two strategies is based on travel time savings as the benefit accrued from the interventions.The study relies on empirical measurements of actual public transport operations to develop models of operating speed for the interventions. Rustenburg Rapid Transit and Tshwane BRT are used as case studies. Ordinary Least Squares (OLS) models were calibrated and tested for conformity with OLS assumptions. Weighted least squares (WLS) was used to correct for heteroskedasticity while generalised least squares (GLS) was used to correct for both heteroskedasticity and serial corelation. The calibrated models were based on operating speed as the response variable while unsignalised intersections per kilometre, signalised intersections per kilometre, stations (stops) per kilometre and land use were predictor variables.To illustrate their application, the developed models were applied to a theoretical 10 km corridor to estimate the operating speed and travel time under various interventions. Travel time was adjusted to account for variations in traffic congestion and passenger demand. Travel time savings were calculated as the difference between travel times for scenarios under consideration and the base scenario (no intervention). Results indicated that both incremental and leapfrog approaches provided positive time savings. The leapfrog approach provided maximum time savings under high demand and traffic congestion. All steps involved in the incremental approach provided a positive time saving. It is concluded that smaller cities and municipalities can follow an incremental approach while bigger cities can leapfrog to complete BRT.

title: Data for paleoclimatic analysis of carbon age-offset in Burial and E5 lakes, Alaska (1998-2025)

description: The stability of arctic permafrost and the carbon it contains are currently threatened by a rapidly warming climate yet the effect of varying climate conditions on erosion and transport of permafrost soils remain unclear. The organic carbon (OC) stored in frozen permafrost soil degrades and ages prior to being transported via fluvial, hillslope, and lakeshore processes or carried by subsurface flow through the active layer and deposited into a lake. This source of OC introduces a component of the lake sediment carbon that is older than the depositional age of the sediment. As a result, the variation in the range of radiocarbon (14C) ages (herein age-offsets) of OC in lake sediment through time can document changes in the relative amount of permafrost-derived OC that was incorporated into the lake sediment. The data in the attached .CSV files was used to examine the relationship between climate, erosion, subsurface hydrology, primary productivity and carbon mobility in the catchments of Burial and E5 lakes in arctic Alaska. Both lakes are underlain by continuous permafrost and have a rich set of paleoclimate proxy data that comprise an approximately 40 thousand year (ka) record of climate and environmental change.

title: Genome of a male Chrysoperla carnea

description: High-molecular-weight DNA was extracted from whole body tissue of one male C. carnea, referred to as BM3, using the standard Qiagen MagAttract HMW kit protocol. HiFi sequencing libraries for BM3 were prepared using the Pacific Biosciences protocols for low DNA input using SMRTbell Express Template prep kit 2.0 with the exception of nuclease treatment during the library step. DNA was fragmented using Megarupter 3. The library was sequenced on one 8M SMRT cell on a Sequel II instrument using Sequel II Binding kit 2.0 and sequencing chemistry v2.0. Loading was performed by diffusion, with pre-extension for 2 hours and a movie time of 30 hours. CCS sequences were generated using the CCS pipeline (SMRT Link v9.0.0.92188) with minimum number passes of 1 and minimum predicted accuracy of 0.99. Cutadapt v3.4 was used to remove any remaining adapter sequences before genome assembly was done using Hifiasm v0.15-r327.

title: Data for paleoclimatic analysis of Hg in lake sediments in Burial Lake, Alaska (1998-2025)

description: Substantial amounts of mercury (Hg) are projected to be released into Arctic watersheds as permafrost thaws amid warmer and wetter conditions. This may have far-reaching consequences because the highly toxic methylated form of Hg biomagnifies rapidly in ecosystems. However, understanding how climate change affects Hg dynamics in permafrost regions is limited due to the lack of long-term Arctic Hg records. Using a 27 thousand year (ka) Hg sediment record from Burial Lake, northwestern Alaska, we used the data in the attached .CSV files, to examine how well-characterized temperature, precipitation, and vegetation shifts affected Hg mobilization in a catchment underlain by permafrost, and the mechanisms by which Hg is transported.
 The tabular data (csv) in this data submission include the data used for the analysis presented in:
