💦 Healthy mangroves experience significant water and sediment movement from tidal flows and river currents. This natural process erodes and deposits soil and sand among the mangroves, resulting in natural tree dieback and colonization. ‼️ However, this should only occur in relatively low levels. If a mangrove forest experiences a lot of boat traffic, storm surge, or unusual sea level rise, it can cause more unnatural levels of erosion. This can lead to increased dieback, limiting the ability of mangroves to protect coastlines from storm surge, wave action, currents, and tides. #CoastalErosion #MangroveConservation #HealthyEcosystems

Today, it the World Reef Awareness Day! 🌍 Since 2014, the Global Coral Reef Monitoring (GCRMN) network for Caribbean has been collecting data on reef conditions. Nowadays, The Caribbean coral reefs are experiencing the Global Bleaching event: This month saw AGRRA's webinar on bleaching in the region and ICRI's webinar on the global state of bleaching with an update from all regions. In a nutshell, a summary of the message from Derek Manzello - NOAA Federal, Coral Reef Watch coordinator: "The entirety of the wider Caribbean is currently much hotter than average. Unfortunately, current sea surface temperatures (SST) across the entire region are as hot, or in many cases, hotter than they were last year at this time. We are already seeing bleaching-level heat stress in the southern Caribbean (Panama, Costa Rica, Nicaragua), which is a full month earlier than what happened last year. NOAA has just predicted that this will be a very active year for tropical storm and hurricane development. In summary, we are trending in the wrong direction. I wanted you all to be aware of this so that you can put plans in place for another potentially bad bleaching year for the Caribbean." This year, we are working on a new Regional Report on the State of #coralreefs in the Caribbean to be published in 2025. We are therefore calling for data contributions in the region. Contact us to join the GCRMN-Caraibbean network and contribute to this crucial regional assessment.

Studies show coral reefs protect tens of thousands of people and billions’ worth of economic assets every year, serving as high-performance seawalls. There's strong business case for why reefs should be maintained and strengthened with disaster funding — investment tens to hundreds of times larger than current conservation budgets. https://ow.ly/173030sJ9rZ #Hurricanes #WEF #SwissRe

#30DayMapChallenge 🗺️ (Day 6: Raster) Palm Beach, located on the Gold Coast of Queensland, Australia, attracts thousands of surfers each year. Recently, noticeable changes have been observed along its coastline. Coastal erosion and accretion are dynamic processes influenced by a range of factors, including natural forces and human activities. Storms, for example, demand more sand to buffer the force of intensified waves, leading to the gradual flattening of dune systems and the formation of storm bars—prominent, cliff-like features that sit further inland from the beach's broad stretch. Additionally, human activities have played a significant role in altering Palm Beach's landscape. The construction of rock walls, especially at the mouths of Tallebudgera Creek and Currumbin Creek, disrupts the natural flow of wave energy. This causes increased erosion as waves reflect off these walls instead of being absorbed by the beach. Pathways built for visitors have also made the area more susceptible to wind erosion. By comparing images of Palm Beach from different periods, basic metrics related to coastal erosion and accretion can be assessed. However, for a more comprehensive analysis, such as calculating the Coastal Vulnerability Index (CVI), further data is needed, including coastal slope, mean wave height, and mean tide range. #30DayMapChallenge2024 #Raster #GIS #CoastalErosion #CoastalAccretion #PalmBeach #GoldCoast #Queensland #Australia #Map

What are living shorelines? 🌊 They are nature based solutions, using materials like plants or oysters, to stabilize shorelines and protect them from erosion. In partnership with Sandbar Oyster Company for our multitrophic project at Sugarloaf Island in North Carolina, these oyster catcher reefs were installed to help wave attenuators stop wave energy from severe storms to protect the coastline, and improve overall water quality. 🎣🐠 No matter where you live, oysters play an important role keeping our water clean, protecting our shorelines, and providing countless economic benefits for those who grow, farm, shell, and cook them! 🦪 #Oysters #Erosion #Shorelines

Trees are so important for stabilising riverbanks and these satellite images, from the floods after Cyclone Jasper, are a great way to show this... They are before and after images at the Barron River. This section of river had minimal riparian vegetation and the riverbanks were already eroding so a lot of farm land washed away. Riparian vegetation is critical for maintaining the resilience of waterways to major disturbances. Vegetation reinforces riverbanks to prevent erosion, minimise the loss of valuable top soil and reduce sediment loads in the Great Barrier Reef lagoon and impacts on coral and seagrass. #floods #wetseason #erosion #soilhealth #sediment #greatbarrierreef

The establishment of the regional coastal erosion monitoring network was the focus of component 3 of the Sandy Shorelines Closing Workshop. The focal points from Antigua and Barbuda, Cuba, Jamaica, and Trinidad and Tobago shared the methodologies used to establish the criteria for monitoring coastal changes across the region. Mark Archibald from Antigua and Barbuda, Isis Hernandez from Cuba, Chanel Raynor from Jamaica, and Christopher Alexis from Trinidad and Tobago stressed the importance, sharing experiences, and collecting data. This segment addressed the necessity of linking shoreline processes with sediment movement in order protect our shorelines. #SandyShorelines #InstitutionalCapacity #SustainableDevelopment #ACSSandyShorelines #CoastalErosion #ClimateCrisis #GreaterCaribbean

The goal of living shorelines should be to augment natural communities in a manner that increases the inherent resiliency of our coastal communities. That is why the primary goals of our #quickreef living shorelines are to create a thriving oyster reef and to remove enough of the pressure on any existing natural marsh to slow its erosion and give it a fighting chance at recovery. #livingshorelines #naturebasedsolutions #marshforward #oysters #coastalresiliency #carteretcountync
