Evaluation of the Good Life Festival : a model for co-produced dementia events
The article presents an evaluation of The Good Life Festival, a co-produced event between people living with dementia, Salford University Dementia Institute, Alzheimer’s Society, Salford and Salford Adventures. This was a new way of working but important because people living with dementia said they thought there should be an event organised ‘for people with dementia by people with dementia’. A dementia friendly evaluation form was circulated asking: did you enjoy the event, did you learn something new, and do you feel more positive about living with dementia following the event. Thirty five of the eighty people who attended completed the evaluation form all of whom said they enjoyed it. 32 (91%) learned something new, and 27 (77%) left feeling more positive about living with dementia. Qualitative feedback is also included in this article including planning group reflections. Recommendations based on what we learned from planning and running the event are provided which includes having a media strategy in place and to send a follow up letter to remind people of information about resources/services advertised on the da
The distribution of iodine and bromine in the sediments of the southwestern Barents Sea
In 42 surface sediments from the southwestern Barents Sea, iodine and bromine ranged from 60 to 828 p.p.m. and 12 to 257 p.p.m., respectively. In the surface environment, both I and Br are related to organic matter; the dependence of halogens on the grain size of the sediment is small...
On the organic carbon maximum on the continental slope of the eastern Arabian Sea
The sedimentary organic carbon maximum on the continental slope off western India is widely believed to be due to the preferential preservation of deposited organic matter at water depths where the intense oxygen minimum intersects the sea floor. This region is considered to constitute one of the modern analogues for the environment of formation of organic-rich sedimentary facies that are common in the geological record. We critically examine the hypothesis that the oxygen minimum in the eastern Arabian Sea is the site of enhanced organic matter accumulation and preservation using analyses of suites of samples with wide geographical coverage along this margin. Organic carbon and nitrogen reach maximum concentrations between 200 and 1600 m depth, whereas the lowest dissolved oxygen contents in the oxygen minimum lie between 200 and 800 m depth. The Corganic/N ratios and the δ13Corganic values show that the organic matter is overwhelmingly marine, and Rock-Eval pyrolysis data demonstrate that the hydrogen indices of the sediments are similar in the sediments accumulating within and outside the oxygen minimum. Thus, the organic carbon maximum extends over a larger depth range than the oxygen minimum (as is also evident on some other slopes), and there is no evidence for preferential preservation of the organic matter within the oxygen minimum. The distribution of organic matter on the western Indian continental margin is controlled by (1) variations in supply (decreasing westward away from the centers of coastal upwelling and also decreasing with increasing water depth), (2) dilution by other sedimentary components, and (3) the texture of the sediments (coarser-grained sediments having lower carbon contents), which is controlled in turn by sediment supply and reworking. The evidence available suggests that the organic carbon maximum on this slope is not related to the position of the oxygen minimum and, consequently, that oxygen minima cannot be used to explain the distribution of organic carbon at intermediate palaeodepths in the geological record
Sinking particle fluxes from the euphotic zone over the continental slope of an eastern boundary current region
We analyze data from sediment traps and current meters moored at two locations 100 km apart over the Vancouver Island continental slope during the spring and summer of 1990. Time-series of sinking particle fluxes, major biogenic components (biogenic silica, calcium carbonate, and particulate organic carbon and nitrogen), and stable isotopic composition (δ13Corganic and δ15Ntotal) were determined on samples obtained with sequential sediment traps moored at 200–250 m depth. Associated water property data were obtained from CTD/Rosette profiles taken during trap service periods and from current meters positioned in the surface layer and near the sediment trap. These data indicate that the two locations (a southern site J and a northern site NJ) were hydrographically distinct during the investigation. At site J, we found evidence for frequent upwelling events and more variability in the upper layer water properties. The main difference in the sinking fluxes of particles between the two sites was the occurrence of a one-week event at the end of May at J that contributed about one third of the total particle flux during the sampling period. Otherwise, the total flux collected during the study and the flux of major biogenic particles were similar at both sites. Silica shells dominated the flux of particles, particularly during the spring and early summer period. At both sites, particulate organic carbon rather than calcium carbonate was the main contributor to particulate carbon fluxes. The δ13Corganic showed marked variations during the sampling period at both sites likely due to variations in the growth rate of phytoplankton and in species composition. In comparison, variations in nitrate availability appear to dominate the changes in δ15Ntotal
Relationship between ferromanganese nodule compositions and sedimentation in a small survey area of the equatorial Pacific
The bulk chemical compositions of ferromanganese nodules recovered from 14 of 38 sediment cores collected from a 230 km2 area of abyssal hill topography in the northern equatorial Pacific (8°20\u27N; 153W; regional depth 5000m) vary nonrandornly between fairly wide limits. The nodules have Mn/Fe ratios ranging from 2.60 to 5.38 and all samples contain todorokite and 8-MnO2. The variation in the Mn/Fe ratio is governed by the total Fe contents of the nodules; Mn varies to a much smaller extent. Cu and Ni contents average about 1% and vary independently of the Mn contents...
