Questions related to Coastal Ecology
We need to calculate the influence of 3 different sources of water intake (river, eutrophicated bay and sea) on the bay, located in the middle of these sources. You can see a map with explanations as the 1st attachment (Slide1).
We have a boat with a flow-through system of sensors, so we measure different parameters every 5 sec (60m approx.). Is it possible to "imagine" the narrow streams of water intake as 3 point-source of "pollution" and calculate the influence of each point on the bay? Like, for example, to understand what source is more responsible for the increased level of pollution: river, bay or sea? Could it be done with kriging in ArcGIS Pro, and then probably visualized the influence with arrows, where the length of the arrow will represent the strength of the influence (2nd attachment, Slide2)?
Or maybe there are other suitable ways to do so? By the way, we don't have information about the speed of the flow in and out of the bay, however, it's probably possible to get it later. But we do have lots of other parameters like salinity, turbidity, fDOM, temperature etc.
I would really appreciate your help and suggestions on what articles I can read about it.
Hi everyone. I'm planning on determining MP presence, size, color, shape, etc., in other words, in doing a visual sorting/characterization of MP accumulated in penaeid shrimp abdominal muscle. Nevertheless, visual sorting becomes more difficult as particle size get smaller, and is time-consuming and is more likely to fall into misidentification errors. Generally, it is recommended to do visual sorting with plastics no less than 500 microns, but I'm anticipating that any plastic embebed in the abdomen is much smaller than that. I was planning to try alcali tissue digestion with KOH and fiber glass microfilters of 2 microns of pore size, and my intention was to observe the filters under a stereoscopic microscope of a minimum of 45X of magnification. But still I'm going to obtain small plastic particles, if any (spoiler: there will be). So my question is if you have any recommendation or alternative method?... observe the filters under a fluorescent microscope using Nile red to facilitate MP discrimination? analyze another tissue? use a greater pore size filter? change the organism... or maybe it is possible to do the job. Espectroscopy methods are not allowed, since it is part of another stage of the project, I just wanna perform visual sorting/characterization.
Thank you very much for your attention.
I am searching for a database presenting the STATUS of Extinction (Red list for example) about COASTAL INVERTEBRATE SPECIES!
What are the basic elements for a good management of the coastal ecosystem? how about the experiences of countries? articles or any links?
Greetings and Good day to all,
I am working through a project and was seeking information from anyone that has had experience using the South Florida Water Management DBHYDRO data platform.
Also if anyone has any information on comparison or analysis of salinities between wet_dry season and then how to graphically show the influence on natural salinity fluctuation/changes and then pinpoint where Freshwater inflow effect those level due to artificial actions like opening_closing levees.
My Gratitude and Thanks
I am not understanding very well the dynamic of benthic exchange in coastal sites and if is a process that normally can occurrs fast (hours to days) or slowly (weeks to decades)?
I need this information to understand the variability of concentration in long-lived and short lived Radium isotopes in a coastal aquifer
Studies from Indian coastal and estuarine waters show that heterotrophic dinoflagellates are negatively correlated with oxygen/ dominant in hypoxic water.
Wenlu Lana., Bangqin Huang., Minhan Dai., Xiuren Ning., Lingfeng Huang., Huasheng Hong. (2009). Dynamics of hetrotrophic dinoflagellates of the Pearl River Estuary. Northern South China Sea. Estuarine, Coastal and Shelf Science 85, 422–430.
Please answer this question.
The zooplankton density estimated in this study ranged from 354-771 cells per ml. That means it is 354000-771000 cells per liter. If you see the available literature from Indian coasts as well as from the same Kalpakkam coast, zooplankton density generally will be in the range of 200000-600000 cells per 10000 liters of seawater. Even many authors have reported similar densities for 100000 liters of seawater. So its unimaginable how such huge numbers were arrived.
Generally, a phytoplankton bloom with 700000 cells per liter density can be seen in naked eye as a distinct layer of green, brown or red colour on sea surface. So, with this high density of zooplankton reported in this paper, the sea will be full of zooplankton. With this density, if you take one liter of seawater, 20-30 % of the volume will be occupied by zooplankton considering the presence of gelatinous species encountered by the authors in this study. Practically, it is just impossible.
I would love to collaborate, as I am trying to record their global occurrence. As for now, there are no records from South American coasts and few from eastern Asia and Australia. But with only 100 species known worldwide there should be plenty more.
I met these two beautiful jellyfish in the Adriatic sea, Strait of Otranto,
can some expert help me in identifying these scifozoa specimens?
I need the district and village wise shape file of Kerala for plotting vulnerability of coastal villages.Can any one provide me with .shp/.smz files for further analysis in spss.
I am currently analysing temporal and spatial zooplankton groups and in many samples from the same time period there appears to be a very high proportion (~90%) of the same group (Cladocera). I have been unable to find literature related to whether zooplankton (specifically cladocera) can develop in blooms under optimum conditions, similar to those of phytoplankton.
If anyone could point me in the direction of any literature related to this topic, it would be greatly appreciated!
As we all know that more and more marine habitats are degenerating because of anthropogenic activities in the ocean and other reseaons, for example, fishing, climate changes. So we need to do something to change the situation.
Can you guys give me some restoration mehods or suggestions, especially for the coastal area.
I am doing a GIS project on different coastal ecosystems and need a representation of such ecosystems. Corals, Mangroves and Seagrass I have, but kelp is missing...Thank you!
While I can find good references for dynamics related to substrate size - community or species on sandy beaches, I would like to find more about potential effects of substrate color (which is finally due to its composition).
Even at temperate latitudes, darker color means higher temperatures under the same radiation. Is there any reported effect of this on life-history traits, or some kind of experiment to test differences in behaviour/physiology of resident species?
I will be increasing T by 2C every few days and need a heater that can do this accurately for a few gallons of seawater
I am trying to use the generalized modes on WAMIT to simulate free surface movement, but when I try to modify the newmodes.dll file WAMIT doesn't working, sending the message: "Error 0007: Error loading import library.newmodes.dll".
I have been trying to modify the dll using Intel Visual Fortran, as recommended in the manual, but it's a more recent version of it. Now I am not sure if I am using the correct procedure, so if anyone could help me with this, maybe with a tutorial or anything, I would be really glad.
Thanks for the help in advance.
I need literature to made a report on integrated coastal management applied to the western Southamerica littoral, mainly Peru. Many places of the work are within the Humboldtian biogeographical region according to Sullivan and Bustamante. But, I have not many experience to build the process to made a plan for ICZM in this zone.
Can you possibly help me to identify the following images?
These were collected from the Chilika lake ecosystem dated 12.12.2008. But proper identification was not made till now.
can anybody help me on this aspect and also can you provide the available literature on this species?
Is anyone working on modeling how changes to coral reefs may change coastal erosion models. This is something I am very interested in getting into and is wondering if anyone would be interested in collaborating or has suggestions on who to speak to. Thanks!
I'm currently working on IUCN Red List assessments for syngnathid fishes. Many are Australian endemics, some of which inhabit seagrass beds. Dedicated surveys and population estimates are few and far between for these species, so it helps with assessments if we know the status of their habitat.
The emerging concept of Anthropocene, era in which human influences modify various environmental properties, has direct implications on coastal research. Indeed, anthropogenic chemical (e.g. metals, pesticides, pharmaceuticals), physical (e.g. microplastics, sediments, temperature) and biological (e.g. invasive species, eutrophication) stressors increasingly affect marine and coastal aquatic systems. Thus, what is the meaning of pollution if the understanding of coastal environments is intrinsically linked to the identification of shifts on contaminant baselines, biology, and oceanographic variables. I will be chairing a session at YOUMARES 7 (link below), and welcome abstracts (deadline June 15) discussing coastal and marine pollution in a broad context including environmental changes related to human interference.
Also contribution and responses posted here might be presented during the session opening.
We are working on a project looking at the relationship between CDOM and DOC across a large gradient of ecosystems. With 10 000+ observations we are still looking for more data.
Anyone aware of possible open data repository?
For clarity, in the spirit of advancing science through open access to publications and data, authorship does not follow from the inclusion of published data. For further information, see guidelines from e.g. EU (https://ec.europa.eu/research/openscience/) and NSF (http://www.nsf.gov/bfa/dias/policy/dmp.jsp).
I am currently modelling the potential distribution of the invasive Caprella mutica and native species of Caprellidae (for starters C. linearis) in the North Sea. From my own work I have obtained several offshore samples in the Dutch part of the North Sea. Furthermore I have received data from colleagues in other countries, but the total dataset is still very small. From literature I have obtained hundreds of presence-only observations (e.g. from Cook et al., 2007). But I found hardly any presence-absence data of Caprellidae.
Is there anyone that has this type of data from the North Sea and is interested in sharing this? Thank you for reading my question!
There are many ecosystem services in the wetlands, such as habitat protection, material circulation. Does anyone have good suggestions for measuring such services?
I was reading the paper "Integrated biomarker response: a useful tool for ecological risk assessement", by Beliaeff et al 2002, and I was trying out the computations as in the example (Computation of IBR at station W3 (Warnemunde Estuary) in March 1995, p1318) and there's one thing I couldn't quite follow.
When the authors write about the minimum value (Min) for all stations and/or surveys for each biomarker, I would think the minimum value (that later on we add to Z to calculate the score S) would be obtained directly from the original dataset (not shown in the article), but what I don't understand is how the Min values are below zero for biomarker levels. I mean, measured enzyme activities are always above zero.
Therefore my questions are: i) how is it we obtain the Min value? or iii) are the minimum values relative values, such as a fold-change in enzyme activity?
In addition, when we have to place a + or - sign in Z (showing upregulation or downregulation in biomarker levels), does that correspond to what is expected in theory or to what was actually observed in the data?
Thanks a lot.
I am currently carrying out a research on climate compatible development through mangrove restoration in Coral Coast Fiji. Unfortunately, there has not been any studies carried out on carbon sequestration rate in this region. However, the Mangroves for Fiji, estimate the carbon sequestration rate as 1 metric ton per hectare per year. I was wondering can I use this figure to calculate the carbon sequestration rate of the replanted mangroves in this region or is there any other method which I can utilise.
If I want to evaluate nutrient enrichment in different areas, such as coastal areas and estuaries, should the evaluation criteria be the same or not? And in the case of different evaluation criteria, how can I compare the different evaluation results to the same extent?
I'm currently writing a paper concerning the collection and identification of interstitial meiofauna communities along different stations on a tourist beach in the Philippines. I'll be collecting and preserving surface sediment samples using PVC corers then isolating meiofauna using a series of sieves. Afterwards, I'll identify the meiofauna up to the family level. I need a good way to calculate and compare the biodiversity indices of the communities along the different sections of the beach.
If you don't mind, could you take a look at these photos (attached) and tell me what you think may have caused the condition in these crabs? They show some curious black lesions on Metacarcinus magister (formerly Cancer magister) we caught during a biological survey about 10 nmi off the mouth of the Columbia River last summer. They were caught in a dredged material disposal site in a few hundred feet of water over silty-sand substrate. Could they be from chitinoclastic bacterial infection or something else?
I appreciate any insight that can be offered. Thanks!
To examine if human activity since 1950s have enhanced the coastal surface productivity I would like to measure some proxies. TOC (%) and BSi (%) are both influenced by preservation and dilution effect from non-organic input. Pigment is used in some cases but difficult to analyze? 13C and 15N?
I am working in a mangrove in Bermuda where Ucides is not reported. Goniopsis is always present on the trees but I do see a crab disappearing into burrows and assumed it was Goniopsis. Your most recent paper indicated that Goniopsis is not a burrower. So I need to determine who this borrower is!
Thanks for a response when you have the time.
Hi, I am looking for information on work being done that examines carbon dynamics in seagrass / eelgrass and salt marsh ecosystems in Canada. I am undertaking some work to determine carbon accumulation rates on the Pacific coast and am interested to see if other work has been done in the region and in Canada.
I'm doing research on Molluscs, using a specific specie named Patella Cochlear. Ecological importance and sexual reproduction of patella cochlear.
Can I have information or links on ecology and biological study of the polychaete species of the Algerian coast, and I would like to have some literature on invasive species and endemic to the Mediterranean Sea. Grazie
I need information or interesting links on the ecology and biology of polychaetes of the Mediterranean Sea (except FAUVEL, 1923 and 1927, Fauchald, 1977). Thanks
Integrated Coastal Management (ICM) is considered as a governance process by Olsen, Lowry and Tobey (1999) and by Olsen and Nickerson (2003). However I realize and support the criterion that “Integrated Coastal Zone Management” (ICZM) is limited to a management process, not specifically a governance one. Governance addresses the values, policies, laws and institutions by which a set of issues are addressed (Olsen, 2003).
I am correlating pCO2 with fluorescence in the Western basin of the Mediterranean Sea. This basin is oligotrophic, but in the spring blooms can occur. I was expecting during this season the pCO2 to decrease due to the biological activity, but the correlation coefficient is positive. What could be the cause behind that?
As distinct from State/local council policy & guidelines & theoretical modelling for climate change and coastal recession,I am interested in looking at adaptive or barrier based models specific to identified "at risk" locations on the Western Victorian Coastline. Sandy beach front communities in particular with minimal land area for urban expansion.
Is it suitable to conduct a mangrove propagule dispersal simulation using MIKE 21 advection/simulation module?
Can anyone suggest what other module in this software is also suitable for this simulation with tidal and salinity as its input field data?
