increased erosion and loss of land to the sea
Higher water levels mean more flood risks, and this leads to less space for intertidal habitats.

The warming of the global climate system
UK seas are heating up and the sea level is rising.

and include parameters such as water temperature (Temp, °C),specific conductivity (SpCond, mS/cm), salinity (Sal, psu), dissolved oxygen both as percent saturation (DO_pct,%) and concentration (DO_mgl, mg/L)
This reminds me of what we have done in class. Temp, salinity, DO, pH etc.

The NERRS SWMP is just one example of how long‐term studies can be thoughtfullydesigned to advance our understanding of coastal ecosystems and processes and address place‐based needs.
They used the same method at many sites and carefully checked their work, which is great for planning and decision making.
-
Without the compre-hensive, standardized data collection over a long period provided by SWMP, we would not be able to elucidatethese patterns, and may in fact incorrectly identify ecosystem‐scale drivers by capturing anomalous years orincomplete long‐term cycles
One season may be weird, many years however, can show the real trend so this is a good point.
-
There are very few mechanisms for funding long‐term studies
If funding is so hard to get, how do they keep this going every year so there aren't any interruptions in tracking the data.
-
communities
Good main point: long-term tracking shows patterns that shorter studies miss.

Estuaries are increasingly vulnerable to the impacts of climate change due to their low elevations and proximity to both river and oceanic influences.
The good thing about this article is that they give what areas and who is at risk as well as simple models showing the salt movement and negative impacts. They also list practical next steps to take to help take action.

FIGURE 3
I really like this figure. It shows a clear before and after and it clearly shows the negative impacts.
-
Even moderate, temporary increases in freshwater discharge or sea level (e.g., storm surge), that would not overtop banks and coastal defense structures on their own, can result in widespread flooding if the events occur concurrently or in close succession
This connects to what I have learned in a few classes, estuary water can seep into riverbanks at high tide and drain back out during low tide. Floodwater on land can soak into the soil. This shows how checking these banks after a flood can be important.

by establishing a 10-km buffer (i.e., the most at-risk coastal area, Cosby et al. 2024) around each estuary.
The study uses a 10 km "near estuary" zone. A question could be if this distance would work for all estuaries?
-
The salinization of soil and groundwater near estuaries may result in food and water insecurity in areas not previously considered at risk of coastal climate impacts.
They used maps to show who is at risk near estuaries. A lot of farms and many large cities sit low and closer to the water. With rising sea levels, storms, and droughts, this can push salt into wells and the soil.

indicator species
They give us data that is pretty easy to follow and specific algae to watch out for. This could potentially help people warn others about harmful blooms earlier on and not just react after the issue occurs.
-
alterations in salinity levels
This shows how salinity and nutrients control which algae appear in estuaries. It explains that small changes in nutrients can bring this system to its tipping point.
-
multiple nutrients
This fits what we have learned in class: more nutrients --> different algae end up taking over, the more nutrients the more algae growth.
-
respectively
They mentioned that they only collected surface water at 0.5 m. Would deeper water or tides change these results?
-
ecosystems.
they tested water in this estuary at different times of the year and different salt levels. They found 63 harmful algae and noticed the algae community changes all of a sudden when nutrients get to a certain level.
