Ryan et al. (2024): data for OTI MPL drone paper
This data repository contains raw data and code for the calculation of planetary boundary layer height (PBLH).The data was collected at One Tree Island in the Southern Great Barrier Reef as part of the Reef Restoration and Adaptation Program's Cooling and Shading fieldwork in March and April 2023. Data files include vertical potential temperature profiles collected by quadcopter drones. Additional data files are raw backscatter collected by a mini-Micropulse Lidar (MPL).PBLH calculated from these two distinct datasets was the subject of Ryan et al. (2024). Code for the data analysis in the comparison is in the Jupyter ipython notebook 'MPL_Drone_Comparison.ipynb'. Additional comments on the comparison and methodology are contained in the Jupyter notebook. All drone and MPL data files are readable with the Jupyter notebook provided the user has installed the packages listed at the top of the file.Initial upload 4 March 2024 at the time of submission of the manuscript to Journal of Geophysical Research: Atmospheres.Correspondence to Robert Ryan: [email protected]</p

Combating chronic bacterial infections by manipulating cyclic nucleotide-regulated biofilm formation
Many pathogenic bacteria can form biofilms in clinical settings with major consequences for the progression of infections. Bacterial biofilm communities are typically much more resistant to both antibiotic treatment and clearance by the immune system in comparison to free-living cells. Therefore, drugs that specifically target the formation or maintenance of biofilms would be very valuable additions to current clinical options. Cyclic nucleotide second messengers, in particular cyclic-diguanosine-GMP (c-di-GMP), are now known to play a major role in biofilm formation, and maintenance, in many bacterial species. In this special report, we will review recent progress toward the development of drugs that interfere with c-di-GMP signaling as a route to control biofilm infections. We will focus on the chronic infections associated with the notorious opportunistic pathogen Pseudomonas aeruginosa, although the principles outlined here are also relevant to most bacterial pathogens.</p

Past and future sea-level rise along the coast of North Carolina, USA
We evaluate relative sea level (RSL) trajectories for North Carolina, USA, in the context of tide-gauge measurements and geological sea-level proxy reconstructions spanning the last ∼11,000 years. RSL rise was fastest (∼7 mm/yr) during the early Holocene and slowed over time with the end of the deglaciation. During the pre-Industrial Common Era (i.e., 0–1800 CE), RSL rise (∼0.7 to 1.1 mm/yr) was driven primarily by glacio-isostatic adjustment, though dampened by tectonic uplift along the Cape Fear Arch. Ocean/atmosphere dynamics caused centennial variability of up to ∼0.6 mm/yr around the long-term rate. It is extremely likely (probability P = 0.95) that 20th century RSL rise at Sand Point, NC, (2.8 ± 0.5 mm/yr) was faster than during any other century in at least 2,900 years. Projections based on a fusion of process models, statistical models, expert elicitation, and expert assessment indicate that RSL at Wilmington, NC, is very likely (P = 0.90) to rise by 42–132 cm between 2000 and 2100 under the high-emissions RCP 8.5 pathway. Under all emission pathways, 21st century RSL rise is very likely (P > 0.90) to be faster than during the 20th century. Due to RSL rise, under RCP 8.5, the current ‘1-in-100 year’ flood is expected at Wilmington in ∼30 of the 50 years between 2050-2100.The final publication is available at Springer via http://dx.doi.org/10.1007/s10584-015-1451-xPeer reviewe
The PAS domain-containing histidine kinase RpfS is a second sensor for the diffusible signal factor of <em>Xanthomonas campestris</em>
A cell-cell signalling system mediated by the fatty acid signal DSF controls the virulence of Xanthomonas campestris pv. campestris (Xcc) to plants. The synthesis and recognition of the DSF signal depends upon different Rpf proteins. DSF signal generation requires RpfF whereas signal perception and transduction depends upon the sensor RpfC and regulator RpfG. Detailed analyses of the regulatory roles of different Rpf proteins have suggested the occurrence of further sensors for DSF. Here we have used a mutagenesis approach coupled with high-resolution transcriptional analysis to identify XC_2579 (RpfS) as a second sensor for DSF in Xcc. RpfS is a complex sensor kinase predicted to have multiple Per/Arnt/Sim (PAS) domains, a histidine kinase domain and a C-terminal receiver (REC) domain. Isothermal calorimetry showed that DSF bound to the isolated N-terminal PAS domain with a Kd of 1.4 µM. RpfS controlled expression of a sub-set of genes distinct from those controlled by RpfC to include genes involved in type IV secretion and chemotaxis. Mutation of XC_2579 was associated with a reduction in virulence of Xcc to Chinese Radish when assayed by leaf spraying but not by leaf inoculation, suggesting a role for RpfS-controlled factors in the epiphytic phase of the disease cycle.</p
