Fig. 3. Best Maximum Likelihood tree based on the data set of concatenated 12S and 16S rDNA, and c-mos sequences. The red clade depicts the Helicops angulatus group. On the left and right sides of a slash (/) are values indicated at nodes for Maximum Likelihood bootstraps (> 75%) and Bayesian Posterior probability values (> 95%), respectively. Green clades represent the paraphyly of Helicops angulatus. The name Helicops pictiventris is currently a junior synonym of H. infrataeniatus, but it appears in the tree exactly as the pertinent sequences appear in the GenBank dataset.

Data for 'Local verses farfield control on South Pacific mode water variability'
<p>The adjoint files contained in two .zip folders here are the output files of two adjoint sensitivity experiments in the South Pacific mode water formation regions, CENTRAL and EASTERN, using ECCOv4r4. The first set of outputs is for the sensitivity of the volume in the Central mode water pool to net heat flux. The folder CENTRAL.zip contains these files which are of the form ADJqnet_CENTRAL.XX.data/.meta, where XX is the timestep. The second set of outputs is for the sensitivity of the volume in the Eastern mode water pool to net heat flux. The folder EASTERN.zip contains these files which are of the form ADJqnet_EASTERN.XX.data/.meta, where XX is the timestep. Both sets of data contained here are the output/sensitivity files for 6 years at 14 day time steps.</p> <p><br>The forward perturbation files contained in four .zip folders here are the output files of four separate forward perturbation experiments, using ECCOv4r4. The first set of outputs is for a forward perturbation experiment related to the Central mode water pool sensitivities, where the perturbation is set in an area of negative sensitivity and uses a negative perturbation in the folder C_ns_np.zip. The folder C_ns_np.zip contains these files which are of the form THETA_mon_mean.XX.data/.meta, SALT_mon_mean.XX.data/.meta, and MXLDEPTH_mon_mean.XX.data/.meta, where XX is the times. The second set of outputs is for a forward perturbation experiment related to the Central mode water pool sensitivities, where the perturbation is set in an area of negative sensitivity and uses a positive perturbation in the folder C_ns_pp.zip. The folder C_ns_pp.zip contains these files which are of the form THETA_mon_mean.XX.data/.meta, SALT_mon_mean.XX.data/.meta, and MXLDEPTH_mon_mean.XX.data/.meta, where XX is the times. The third set of outputs is for a forward perturbation experiment related to the Central mode water pool sensitivities, where the perturbation is set in an area of positive sensitivity and uses a negative perturbation in the folder C_ps_np.zip. The folder C_ps_np.zip contains these files which are of the form THETA_mon_mean.XX.data/.meta, SALT_mon_mean.XX.data/.meta, and MXLDEPTH_mon_mean.XX.data/.meta, where XX is the times.

The folder C_ps_pp.zip contains these files which are of the form THETA_mon_mean.XX.data/.meta, SALT_mon_mean.XX.data/.meta, and MXLDEPTH_mon_mean.XX.data/.meta, where XX is the times. All sets of data contained here are the output/forward perturbation files for 3 years at 14 day time steps, starting when the perturbation begins. The THETA and SALT files from the forward perturbation experiments are used to create neutral density files using the gibbs seawater toolbox in MATLAB. These perturbed neutral densities are then used to find the difference the perturbation makes in relation to a control experiment.</p> <p><br> <br>Paper abstract: In the South Pacific mode water formation region, central and eastern pools of mode water have been found to be linked to winter mixed-layer thicknesses that vary strongly interannually and out of phase across the basin. This mixed-layer variability is associated with peaks in sea level pressure variability at a quasi-stationary anomaly situated between the two pools. To investigate how surface forcing, as well as the propagation of upstream anomalies, affects the formation of these mode water pools, a set of adjoint sensitivity experiments with a density-following feature are conducted. Adjoint sensitivities reveal local cooling can lead to an increase in mode water pool volume through mixed-layer depth changes and lateral density surface movement. In addition, upstream warming along the Antarctic Circumpolar Current can lead to an increase in mode water pool volume through lateral density surface movement. Optimal conditions for mode water formation involve a combination of local cooling and upstream warming of mode water formation sites. Hence, South Pacific mode water variability is particularly sensitive to atmospheric modes which lead to a dipole in heating across the formation sites.</p>

To investigate how external forcing affects the stratification in mode water formation regions in the Southern Ocean, we conduct a set of adjoint sensitivity experiments. The objective function is the annual-average stratification over the mode water formation region, which is evaluated from potential temperature and salinity adjoint sensitivity experiments. The analysis of impacts, from the product of sensitivities and forcing variability, identifies the separate effects of the wind stress, heat flux, and freshwater flux, revealing that the dominant control on stratification is from surface heat fluxes, as well as a smaller effect from zonal wind stress. The adjoint sensitivities of stratification to surface heat flux reveal a surprising change in sign over 2 years lead time. Surface cooling leads to the expected initial local decrease in stratification. However, there is a delayed response to surface cooling leading to an increase in stratification. This delayed response in stratification involves atmospheric damping of the surface thermal contribution, so that eventually the oppositely-signed advective haline contribution dominates. This two-phase response of stratification is found to hold over mode water formation regions in the South Indian and Southeast Pacific sectors of the Southern Ocean, where there are strong advective flows linked to the Antarctic Circumpolar Current.</p>

By animal, water, or wind: can dispersal mode predict genetic connectivity in riverine plant species?
<div class="page"> <div class="section"> <div class="layoutArea"> <div class="column"> <p>Seed dispersal is crucial to gene flow among plant populations. Although the effects of geographic distance and barriers to gene flow are well studied in many systems, it is unclear how seed dispersal mediates gene flow in conjunction with interacting effects of geographic distance and barriers. To test whether distinct seed dispersal modes (i.e. hydrochory, anemochory, and zoochory) have a consistent effect on the level of genetic connectivity (i.e., gene flow) among populations of riverine plant species, we used unlinked single-nucleotide polymorphisms (SNPs) for eight co-distributed plant species sampled across the Rio Branco, a putative biogeographic barrier in the Amazon Basin. We found that animal-dispersed plant species exhibited higher levels of genetic diversity and lack of inbreeding as a result of the stronger genetic connectivity than plant species whose seeds are dispersed by water or wind. Interestingly, our results also indicated that the Rio Branco facilitates gene dispersal for all plant species analyzed, irrespective of their mode of dispersal. Our findings indicate that seed dispersal mode and riverscape features can greatly impact genetic structure, representing reliable predictors of genetic connectivity in riverine plant species. These results may help improve conservation and management policies in Amazonian riparian forests, where degradation and deforestation rates are high.</p> </div> </div> </div> </div>

S-MODE PRISM Level 2 Water Surface Chlorophyll-a Version 1
This dataset contains estimated chlorophyll-a and particulate organic carbon concentration data from the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) during the IOP1 campaign conducted approximately 300 km offshore of San Francisco during Fall 2022. S-MODE aims to understand how ocean dynamics acting on short spatial scales influence the vertical exchange of physical and biological variables in the ocean. The Portable Remote Imaging Spectrometer (PRISM) is an airborne instrument package that is mounted on the GIII aircraft which flies long duration detailed surveys of the field domain during deployments. PRISM contains a pushbroom imaging spectrometer operating at near-UV to near-IR wavelengths (350-1050 nm), which produced high temporal resolution and resolve spatial features as small as 30 cm. PRISM also has a two-channel spot radiometer at short-wave infrared (SWIR) band (1240 nm and 1640 nm), that is co-aligned with the spectrometer and is used to provide accurate atmospheric correction of the ocean color measurements. Level 2 chlorophyll-a data are available in netCDF format.
